Figure shows a small hydraulic jack. At this instant, a 10-lb force is applied to the handle. This causes the 3.5-in. link to rotate clockwise at a constant rate of 5 rad/s. The weight of links 2 and 3 is negligible, and link 4 is 1.5 lb. Determine the following:

1. The linear acceleration of the piston,

2. The inertial force of link 4,

3. The pin forces, and

4. The force developed on the piston due to the hydraulic fluid.
