Two blocks having the weights and position shown, rest on a frame which rotates about its vertical axis at a constant speed. The coefficient of friction between the blocks and the frame is 0.02 neglecting the weight and friction of the pulley, at what speed in RPM will the blocks start to slide? What is the tension in the cord at this instant.?

Question 2 A car has a mass of 4 Mg and the center of mass at G = 400mm from the ground. The front wheels are 1.3 m and rear wheels are 0.8 m from the centre of gravity. Coefficient of kinetic friction between the wheels and the road is 0.2. Determine the acceleration if the rear driving wheels are always slipping and the front wheels are free to rotate. Neglect the mass of the wheels.

The uniform cylinder has a mass of 30.0kg and is rotating about a horizontal axis through O at 1200 rpm. The coefficient of kinetic friction between the cylinders and braking levers is 0.200. If the spring tension is 100 N, calculate the time required for the cylinder to stop spinning.

The cylinder is uniform and has a mass of 5.00 kg. It is released from rest.a) Calculate the least coefficient of friction between the cylinder and the plane for which the cylinder will roll without slipping.b) Calculate the acceleration of the center of mass G of the cylinder if it rolls without slipping.
