Question

Площадь малого поршня гидравлической машины в 50 раз меньше, чем большего. Нк малый поршень поставили гирю весом 20Н. Определите вес груза, который надо положиь на большой поршень.

Answer 1

Дано:F1=20H
l1-в50раз
F2-?
Hрешение:тут формула такова:
F1/F2=S1/S2; отсюда   F2=F1*S1/S2=20H*50=1000
Hвот и ответ! нужно приложить силу 1000H к короткому плечу рычага, чтобы установить равновесие!!!

Answer 2

Calculation of Weight on the Large Piston

To determine the weight of the load that needs to be placed on the large piston, we can use the principle of Pascal's law, which states that the pressure exerted on a fluid in a closed system is transmitted equally in all directions.

Given that the area of the small piston is 50 times smaller than the area of the large piston, we can use the following equation to calculate the weight on the large piston:

Pressure on small piston = Pressure on large piston

The pressure on the small piston can be calculated using the formula:

Pressure = Force / Area

We are given that the weight on the small piston is 20 N. Let's assume the area of the small piston is A, and the area of the large piston is 50A.

Using the equation for pressure, we can write:

20 N / A = Weight on large piston / (50A)

Simplifying the equation, we get:

Weight on large piston = (20 N / A) * (50A)

The area A cancels out, and we are left with:

Weight on large piston = 1000 N

Therefore, the weight of the load that needs to be placed on the large piston is 1000 N.

Please note that the specific values for the areas of the pistons were not provided in the question, so we used variables A and 50A to represent the areas.
