The rod of the fixed hydraulic cylinder is moving to the left with a speed of 10

Question

The rod of the fixed hydraulic cylinder is moving to the left with a speed of 100 mm/s and this speed is momentarily increasing at a rate of 400 mm/s each second at the instant when sA = 425 mm. Determine the tension in the cord at that instant. The mass of slider B is 0.5 kg, the length of the cord is 1050 mm, and the effects of the radius and friction of the small pulley at A are negligible. Find results for cases (a) negligible friction at slider B and (b) mu k = 0.40 at slider B. The action is in a vertical plane.

Explanation / Answer

Use forces F=ma along with force of tension and force of friction. It should be fairly easy if you set up a free body diagram.
