The rod of the fixed hydraulic cylinder is moving to the left with a speed of 114 mm/s and this speed is momentarily increasing at a rate of 470 mm/s each second at the instant when sa = 395 mm. determine the tension in the cord at that instant. the mass of slider b is 0.57 kg, the length of the cord is 1052 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) μk = 0.42 at slider b. the action is in a vertical plane.
