Question

Площадь малого поршня гидравлической машины S1=5 см², на него действует сила F1=100 Н. Площадь большого поршня S2= 100 см². Каково Давление воды на большой поршень?

Answer 1

Дано: Площадь1 = 5см2 площадь2 = 100см2  сила1=100ньютон найти: силу2-?
Формула: сила2/сила1 = площадь2/площадь1
Решение: Сила2 = 100*100 / 5 = 10000/5= 2000 Ньютон
 

Answer 2

Calculation of Pressure on the Large Piston

To calculate the pressure 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.

According to the given information: - Area of the small piston (S1) = 5 cm² - Force acting on the small piston (F1) = 100 N - Area of the large piston (S2) = 100 cm²

Using Pascal's law, we can equate the pressure on the small piston (P1) to the pressure on the large piston (P2):

P1 = P2

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

P1 = F1 / S1

Substituting the given values:

P1 = 100 N / 5 cm²

Now, we can equate P1 to P2:

P1 = P2

100 N / 5 cm² = P2

To find the pressure on the large piston (P2), we can rearrange the equation:

P2 = (100 N / 5 cm²) * S2

Substituting the given value of S2 (100 cm²):

P2 = (100 N / 5 cm²) * 100 cm²

Simplifying the equation:

P2 = 1000 N

Therefore, the pressure on the large piston is 1000 N.
