QUESTION
The drawing below shows a hydraulic chamber in which a spring (spring constant = 1650 N/m) is attached to the input piston (A1 = 16.3 cm2), and a rock of mass 40.7 kg rests on the output plunger (A2 = 65.1 cm2). The piston and plunger are nearly at the same height, and each has a negligible mass. By how much is the spring compressed from its unstrained position?Link to image: https://loncapa2.physics.sc.edu/res/wiley/cutnell/Physics_7ed/Chap11/graphics/cutj1137.gif
