Question

In the hydraulic press used in a trash compactor, the radii of the input piston and the output plunger are 6.2 ✕ 10^{-3} m and 5.1 ✕ 10^{-2} m, respectively. If the height difference between the input piston and the output plunger can be neglected, what force is applied to the trash when the input force is 380 N.

Step 1

Given,

Step 2

Pascale’s principle: A change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid.

Applying Pascale’s principle in hydraulic lift, pressure on the wall of plunger is equal to the pressure on the wall of piston.

Step 3

Rearrange and substitute the given va...
