Question

площадь малого поршня гидравлической машины 5 см (квадратных) , на него действует сила 100Н. Площадь большого поршня 100см(квадратных) .какого давление воды на большой поршень? какую силу надо приложить к нему, что бы поршни находились в равновесии???

Answer 1

По-моему так, 100*100/5=2000Н

Answer 2

Calculation of Pressure and Force in a Hydraulic Machine

To calculate the pressure and force in a hydraulic machine, we need to use the formula:

Pressure = Force / Area

Given the following information: - Area of the small piston (S1) = 5 cm² - Force acting on the small piston = 100 N - Area of the large piston (S2) = 100 cm²

We can calculate the pressure on the large piston and the force required to maintain equilibrium.

Calculation of Pressure on the Large Piston

To calculate the pressure on the large piston, we can use the formula:

Pressure = Force / Area

Substituting the values into the formula, we get:

Pressure on the large piston = Force / Area of the large piston

Pressure on the large piston = 100 N / 100 cm²

Converting the units to match, we have:

Pressure on the large piston = 100 N / 10000 cm²

Simplifying the expression, we get:

Pressure on the large piston = 0.01 N/cm²

Therefore, the pressure on the large piston is 0.01 N/cm².

Calculation of Force Required for Equilibrium

To calculate the force required to maintain equilibrium, we can use the formula:

Force = Pressure x Area

Substituting the values into the formula, we get:

Force required for equilibrium = Pressure on the large piston x Area of the large piston

Force required for equilibrium = 0.01 N/cm² x 100 cm²

Converting the units to match, we have:

Force required for equilibrium = 0.01 N/cm² x 10000 cm²

Simplifying the expression, we get:

Force required for equilibrium = 100 N

Therefore, a force of 100 N needs to be applied to the large piston to maintain equilibrium.
