Question

Сила давления,действующая на поршень гидравлического пресса площадью 180 см/2,равна 18 000 Н. Площадь меньшего поршня 4 см/2, какая сила приложена к меньшему поршню?

Answer 1

F2=S2             F2=F1*S2

F1  S1                     S1

 

F2=18000H *4см2 =400Н

           180см2

 

Answer 2

Calculation of Force on the Smaller Piston

To calculate the force applied to the smaller 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: - Area of the larger piston (A1) = 180 cm^2 - Force applied to the larger piston (F1) = 18,000 N - Area of the smaller piston (A2) = 4 cm^2

We can use the formula:

F1 / A1 = F2 / A2

where: - F1 is the force applied to the larger piston - A1 is the area of the larger piston - F2 is the force applied to the smaller piston (what we want to find) - A2 is the area of the smaller piston

Substituting the given values into the formula, we have:

18,000 N / 180 cm^2 = F2 / 4 cm^2

Simplifying the equation, we find:

F2 = (18,000 N / 180 cm^2) * 4 cm^2

Now, let's calculate the force applied to the smaller piston:

F2 = (18,000 N / 180 cm^2) * 4 cm^2 = 400 N

Therefore, the force applied to the smaller piston is 400 N.
