Q. A hydraulic chamber with a spring (spring constant = 1600 N/m) attached to the input piston and a rock of mass 40kg resting on the output plunger. The piston and plunger are nearly at the same height, and each has the negligible mass. By how much is the spring compressed from its unstrained position?
