Question

In the previous problem if the green piston is depressed 0.59 meters, how far up would the red piston move to the nearest thousandth of a meter?

In the hydraulic lift at the left the red piston has a cross-sectional area of 0.77 m^2 and the green piston a cross-sectional area of 0.1 m^2 and the force F1 = 141 N. What weight to the nearest newton can this configuration lift? In the previous problem if the green piston is depressed 0.59 meters, how far up would the red piston move to the nearest thousandth of a meter?

Explanation / Answer

Pressure @ each piston is the same => 141N / 0.1 m^2 = F2 / 0.77 m^2 => F2 = 1085.7 N.

Work is the same, so 141 N * 0.59m = 1085.7 N * h => h = 0.0766 m
