Determine the acceleration of the system and the tension in each cable. The inclined plane is smooth, and the coefficient of kinetic friction between the horizontal surface and block C is (P)c = 0.2. |5 kg 10 kg 25 kg 30 (H)c = 0.2-

The rod of the fixed hydraulic cylinder is moving to the left with a speed of 94 mm/s and this speed is momentarily increasing at a rate of 440 mm/s each second at the instant when SA = 355 mm. Determine the tension in the cord at that instant. The mass of slider Bis 0.77 kg, the length of the cord is 950 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) p = 0.42 at slider B. The action is in a vertical plane. 220 mm Answers: 0.77 kg B (a) Negligible friction: T= i (b) Uk=0.42: T= i N N

The 935-kg motorized unit A is designed to raise and lower the 580-kg bucket B of concrete. Determine the average force R which supports unit A during the 5.2 seconds required to slow the descent of the bucket from 4.4 m/s to 0.9 m/s. Analyze the entire system as a unit without finding the tension in the cable. B Answer: R = i kN
