A belt of negligible mass passes between cylinders A and B and is pulled to the right with a force P. Cylinders A and B weigh, respectively, 5 and 20 lb. The shaft of cylinder A is free to slide in a vertical slot and the coefficients of friction between the belt and each of the cylinders are µs = 0.50 and µk = 0.40. For P = 3.6 lb, determine (a) whether slipping occurs between the belt and either cylinder, (b) the angular acceleration of each cylinder.

Blocks A, B, and C are placed as in the figure(Figure 1) and connected by ropes of negligible mass. Both A and B weigh 25.0 N each, and the coefficient of kinetic friction between each block and the surface is 0.32. Block C descends with constant velocity.

3. Blocks AA and BB of mass 10 kg and 4 kg respectively, are placed on the inclined plane and released. The coefficients of kinetic friction between the blocks and the inclined plane are μAμAmuA = 0.1 and μBμBmuB = 0.5. Neglect the mass of the link

Knowing that the coefficient of static friction between the tires and the road is 0.8 for the automobile (m=1050 kg) shown, determine   1-normal reaction at front wheel (N), the car is assumed rear wheel drive. 2-  normal reaction at rear wheel (N), the car is assumed rear wheel drive. 3- maximum acceleration (m/s2), the car is assumed rear wheel drive.
