The drawing shows a hydraulic chamber with a spring (spring constant = 1600 n/m) attached to the input piston and a rock of mass 40.0 kg resting on the output plunger. 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?

Explanation:

Given:

Now, the force due to the mass:

Compression in Spring:
