Today on the program fable "Swan, Pike and Cancer" famous Russian fabulist Ivan Andreevich Krylov, charming three problems in physics and delightful five illustrations for a fable performed by eminent Soviet artists - Evgeny Mikhailovich Racheva, Alexei Mikhailovich Laptev, Peter Petrovich Repkin, Vladimir Georgievich Arbekova, Mikhail Afanasyevich Taranova.
SWAN, PIKE AND CANCER
When there is no agreement among comrades,
Their business will not go well,
And nothing will come out of it, only flour.
──────────
One day Swan, Cancer, yes Pike
Carried with luggage, they took it,
And together the three all harnessed themselves to it;
They are climbing out of their skin, but the cart is still not moving!
The luggage would have seemed easy for them:
Yes, the Swan breaks into the clouds,
Cancer moves back, and Pike pulls into the water.
Who is to blame among them, who is right, is not for us to judge;
Yes, only things are still there.

He is best known as the author of 236 fables, collected in nine lifetime collections (published from 1809 to 1843). Along with the fact that most of the plots of Krylov's fables are original, some of them go back to the fables of La Fontaine (who, in turn, borrowed them from Aesop, Phaedrus and Babrius).

For the curious:
According to one version, the plot of Krylov's fable "Swan, Pike and Cancer" contains a hint at the events of that time, namely, the dissatisfaction of the Russian society with the actions of the political allies of Emperor Alexander I (the war of the Sixth Coalition against Napoleon); according to another version, contemporaries associated the plot of the fable with ugly turmoil between members of the State Council - the reforms and committees started by Alexander I were unable to move the autocracy, which was deeply bogged down in disagreements, from its place. In this, from a political point of view, Ivan Andreevich Krylov was still right ;-) And these political turmoil masterfully portrayed in his illustrations for the fable "Swan, Pike and Cancer" one of the most popular children's illustrators of the last century Evgeny Mikhailovich Rachev

What grandfather Krylov really hinted at is unknown to us, but the quote: “The swan breaks into the clouds, the Cancer moves back, and the Pike pulls into the water”, as well as the title of the fable "Swan, Pike and Cancer" are used in our days to characterize confusion and lack of coherence in some business ...
And now ... we dive headlong into my adored physics ;-)
performed by Yakov Isidorovich Perelman
The story of how "a swan, a crayfish and a pike took on a load of luggage" is known to everyone. But hardly anyone has tried to consider this fable from the point of view of mechanics. The result is not at all similar to the conclusion of the fabulist Krylov.
Before us is a mechanical problem for the addition of several forces acting at an angle to one another. The direction of the forces is defined in the fable as follows:
... The swan breaks into the clouds,
The crayfish backs up, and the pike pulls into the water.
Rice. 1: The problem of Krylov's swan, crayfish and pike,
solved according to the rules of mechanics
This means (see Fig. 1) that one force, the thrust of a swan ( OA), directed upwards; other, pike pull ( OB), - sideways; third, cancer cravings ( OC), - back. Let's not forget that there is also a fourth force - the weight of the cart, which is directed vertically downwards. The fable states that “the cart is still there,” in other words, that the resultant of all the forces applied to the cart is zero.
resultant ( OD) should drag the cart into the river.
Is it so? We will see. The swan, rushing towards the clouds, does not interfere with the work of cancer and pike, it even helps them: the thrust of the swan, directed against gravity, reduces the friction of the wheels on the ground and on the axle, thereby lightening the weight of the wagon, and perhaps even completely balancing it, because the load is small (). Assuming for simplicity the last case, we see that only two forces remain: the thrust of the crayfish and the thrust of the pike. Regarding the direction of these forces, it is said that "The cancer moves back, and the pike pulls into the water". It goes without saying that the water was not in front of the wagon, but somewhere on the side (the Krylov workers did not gather to sink the wagon ;-) This means that the forces of the cancer and the pike are directed at an angle to one another. If the applied forces do not lie on one straight line, then their resultant cannot be equal to zero.
Acting according to the rules of mechanics, we build on both forces OB and OC parallelogram, its diagonal OD gives the direction and magnitude of the resultant. It is clear that this resultant force must move the cart from its place, especially since its weight is fully or partially balanced by the thrust of the swan. Another question - in which direction will the cart move: forward, backward or sideways? It depends already on the ratio of forces and on the magnitude of the angle between them.
Readers who have some practice in the addition and decomposition of forces will easily figure it out even in the case when the force of the swan does not balance the weight of the wagon; they will be convinced that even then the cart cannot remain motionless. Under only one condition, the cart may not move under the action of these three forces: if the friction at its axles and on the roadbed is greater than the applied efforts. But this is inconsistent with the assertion that “The luggage would seem easy for them”.
In any case, Krylov could not confidently assert that "the cart is still not moving", that "things are still there." This, however, does not change the meaning of the fable ;-)

And yet ... I invite readers to look into the wonderful collection of problems in physics for applicants to universities(Bendrikov, G.A., Bukhovtsev, B.B., Kerzhentsev, V.V., Myakishev G.Ya.) which, in our physical and mathematical school, the people christened "Swan, Pike and Cancer Bukhovtsev" for the picture on the cover of the problem book ;-)
Let's translate Ivan Andreevich Krylov's fable "Swan, Pike and Cancer" into the language of formulas ;-)
SOLUTION OF THE PROBLEM OF SWAN, PIKE AND CANCER
From the collection "Problems in Physics for Applicants to Universities"
"Swan, Pike and Cancer Bukhovtseva" ;-)
Authors: Bendrikov, G.A., Bukhovtsev, B.B., Kerzhentsev, V.V., Myakishev G.Ya.
The task:
What path s during time t will “skid” the load m if the pike and the crayfish pull it in opposite directions horizontally with the forces F 1 and F 2 , and the swan pulls with the force F 3 in the same direction as the crayfish, but at an angle α to the horizon? The coefficient of friction between the wheels and the ground is k. The initial speed of the car is v 0 = 0. The forces acting on the car are shown in fig. 2
Rice. 2: Acting forces
Let's consider three options for solving the problem.
First option:
Let's say: mg< F 3 sinα (F 3 – сила с которой тянет воз лебедь)
In this case, the cart will not go “skid”, but will rise into the air and eventually end up “in the clouds” ;-) Thus, the proposed solution to the problem goes beyond its conditions, since cancer and pike will no longer be pull the cart in opposite directions.
Second option:
Assume that: mg > F 3 sinα
and
F \u003d kN \u003d k (mg - F 3 sinα) > | F 2 – F 1 + F 3 cosα |
where N is the reaction force of the earth's surface, it turns out that "things and now there";-) - the cart won't budge!
thus: s = 0
Third option:
Assume that: mg > F 3 sinα
and
F \u003d kN \u003d k (mg - F 3 sinα)< | F 2 – F 1 + F 3 cosα |
And also given that: s = at 2 /2 we have:
Here, the “+” sign refers to the case F 1 > F 3 cosα + F 2 and means that the cart will move after the pike, and the “–” sign refers to the case F 1

Member of the Union of Cinematographers of the USSR.
And finally, let's play a little more with Ivan Andreevich Krylov's immortal fable "Swan, Pike and Cancer" ;-) Let's treat ourselves physics and bold satire- a free interpretation of the fable in accordance with the realities of our current life ;-)
In the condition of this problem, we will assume that the swan, crayfish and pike really do not move the cart, given that their forces are equal in absolute value and that there is no friction between the cart and the earth ... I will not argue that the formulation of the problem is somewhat absurd ;-) difficult imagine that the forces of a swan, cancer and pike are equal in modulus, but in mathematics and physics you really need to be able to abstract!!!
We will not leave biophysics without attention and replenish our knowledge with some interesting things ;-) and also dilute the bitterness of satire with delightful illustrations performed by eminent Soviet artists Vladimir Georgievich Arbekova and Mikhail Afanasyevich Taranova.
Lyrical digression for the curious ;-)
Sometimes biophysical, sometimes satirical…
Swan. Swans are different ;-) mute swan, trumpeter swan, tundra swan, whooper swan ... Body length varies from 120 to 180 cm, wingspan from 200 to 240 cm, weigh from 5–6 to 8–13 kg. The main food is aquatic plants and small animals in them (mollusks, water donkeys). In flight, the speed can reach 60-80 km / h. Protecting its offspring, a swan with a blow of its wing can easily break the skull of a red fox or a terrible gray wolf without much difficulty.
Cancer. The body length of the broad-clawed crayfish can reach 25 cm or more. The crayfish feeds on plant foods and mostly dead animals... live animals only under a successful set of circumstances ;-) In the river, the crayfish both swims and walks head first. And backs away when something is frightened. If the crayfish noticed a danger, a large predatory fish, for example, then, escaping, it develops a decent “reverse speed”, which is helped by its indispensable tail assistant. But this speed is very modest and is no more than 2 km / h.
Pike. Body length up to 1.5 m, weight up to 35 kg (usually up to 1 m and 8 kg). Pike is a predator (feeds mainly on fish). The speed with which the pike attacks its prey is 100 km / h, although the duration of the throw is only a fraction of a second. Caught on a fishing hook, an adult pike can easily snatch a fishing rod from the hands of even an experienced fisherman.
Arbekov Vladimir Georgievich(10/21/1927 - 03/17/2000) - Soviet director of animated films, animator.
And now the most interesting - dive from the abyss of biophysics into satire!
"We adjust the data" to the condition of the problem;-) Let's assume that:
Cancer we still have that good fellow! On bloody, but very satisfying bread, bestowed in the 90s of the last century, and at someone else's expense, albeit foul-smelling ... Fattened to such a glory that one cannot say in a fairy tale or describe with a pen !!!
Swan we have a very young, not yet really fledged, and even with broken wings: - (The ongoing and irresponsible education reform, depressive and corrupting propaganda in the media ... - steadily crippling generation after generation, doing their job! They break not only wings, but also spoil the soul!!!
Pike we have a catastrophically old, appreciating all the charms of the barbarian pension reform 2018 in full... and therefore infinitely tired, terribly sick - barely alive :-(
This is how Mother Russia is being dragged in different directions by the utterly disgruntled oligarchs, the restless, confused youth and the dying Soviet generation... All this would be funny if it weren't so sad...
Forces are not equal! Moreover, if we take into account that this case force is measured not in newtons, but in rubles ... It's sad!!! Physics and life sometimes categorically diverge, but literature can unite them! Satire - denouncing and scourging irony!!! Thank you Grandpa Krylov for that!!! The fable "Swan, Pike and Cancer", published in 1816, has not lost its relevance even today, despite the change of scenery and characters ;-) Well, we, within the framework of this publication, agreed to abstract; -)

So, the forces of the swan, crayfish and pike are equal in modulus :-)
SOLUTION OF THE PROBLEM OF SWAN, PIKE AND CANCER
From the collection "Selected Problems in Physics"
Authors: Shaskolskaya M.P., Eltsin I.A.
1946 Olympics. I tour for 7th grade students
The task:
In what cases do the heroes of Krylov's fable, the swan, the cancer and the pike, really not move the cart, if we assume that their forces are equal and that there is no friction between the cart and the earth? Accompany the answer with pictures.
Decision. 1st case
All three forces, equal in absolute value, are located in the same plane and make angles of 120 ° with each other, the resultant of these forces is equal to zero - fig. 3a.
Decision. 2nd case
Cancer and pike pull the cart in opposite directions, and the swan - vertically upwards - fig. 3b, and the traction force of the swan is less than the weight of the cart (the last condition, however, is not specified in the fable ;-)

“And things are still there” - this expression has long become a favorite saying when it comes to a case that does not move in any way, despite numerous, and as it turns out, futile efforts. Today it is already hard to believe, but this phrase did not arise unaddressed, that is, from the people. The author of this vivid expression is the famous Russian fabulist, poet, publicist Ivan Andreevich Krylov.
A bit of history
In 1814, namely on May 12, the collection “New Fables” was published, where a small but bright fable “Swan, Cancer and Pike” was presented, at the end of which this famous phrase was, which became a folk proverb.
There is an opinion that the fable has historical overtones. Ivan Krylov subtly alludes to the State Council, whose members experienced such disagreement that Emperor Alexander I himself was forced to intervene in the work of the body.
It is worth noting that other researchers note that the fable was so often used to characterize the work of one or another administrative institution that the legend of the State Council was born, and the author actually did not mean anything like that. Unfortunately, we don't know the truth.
The plot, content and main characters of the fable
Once a Swan (an animal that flies), a Pike (an animal that swims) and a Cancer (used to back away) decided to lead a cart with heavy luggage. For this, friends were harnessed to a cart in the likeness of horses.
Everyone tried their best, but it was of no use. The swan strove to fly up, the Pike to hide in the water, and the Cancer stubbornly dragged the cart back. The task would not seem so impossible if all the animals worked together. But it turned out quite differently.
At the conclusion of the fable, Krylov wisely remarks that it is not our business to look for the right and the wrong, but only the cart remained standing still.
Moral of the fable
Getting acquainted with the fables of Ivan Andreevich, you never get tired of wondering how he can raise such important personal and social problems in such a capacious light form with an ironic understandable language! A funny fable of small size (only 12 lines) draws a whole story with deep subtext.
The heroes of the fable - Swan, Pike and Cancer do not carry any specific personal characteristics (for example, fox-cunning, hare-cowardice, wolf - anger, greed), but rather personify different nature, habitat, behavior, habits, etc. d. The bird must fly, the pike must swim, and the crayfish must walk backwards. Only friendship, harmony, the ability to negotiate and organize can unite them into some kind of unified force.
So it is in life: how often people, different in character, with their worldview cannot get along and organize a common cause. Unwillingness to yield, stubbornness, inability to conduct a dialogue leads, if not to collapse, then to the absolute absence of results.
When embarking on any business, it is important not only to have a single chosen goal, but to coordinate actions to achieve the goals. Sometimes, in order to realize a common cause, it is necessary to deviate from one's principles, to show will, to "hold" one's character, to yield. The heroes of the fable not only do not do this, but do not even realize what their problem is. Unfortunately, in life too often people are closed in captivity of their habits, and therefore are not able to see the essence of the issue.
Krylov devoted more than one fable to friendship, comradeship, harmony, so it was in these such simple and necessary concepts that he saw the path to human happiness.
The fable "Swan, Cancer and Pike" is ideal for learning from a very young age - bright characters, a visual plot, simple language and a small form make the fable a faithful assistant in raising a child with the right life values.
