Question

1. Would the operation of the hydraulic press moved to the Moon differ?

2. The small piston of a hydraulic press with an area S1 = 0.001 m2 is subjected to a force F1 = 20 N. What is the magnitude of the force and pressure acting on a large piston with an area S2 = 0.1 m2?

Answer 1

1.

The operation of the hydraulic press is not depends on gravitational acceleration $g,$ $A_1=A_2.$

2.

$p_2=p_1=\frac{F_1}{S_1}=20~kPa,$

$F_2=F_1 \frac{S_2}{S_1}=2~kN.$
