A trolley A has a simple pendulum suspended from a frame fixed to its deck A block B is in contact on its vertical side. The trolley is on horizontal rails and accelerates towards the right, such that the block is just prevented from falling. If the value of coefficient of friction between A and B is 0.5 find the value of the inclination of the pendulum to the vertical.

A block is pressed towards a vertical wall using a horizontal force equal to n times its weight which prevents the block from sliding down.Then coefficient of static friction between the block and the wall is?

A block of mass 2kg is placed on a trolley of mass 20 kg free to move on a frictionless floor. What are the frictional force, accelerations of the block and trolley if the block is pulled by a force of 3 N ? The coefficient of friction between block and trolley is 0.25. What will be the values of all three if the block is pulled by 8 N force ? At what value of the applied force will the bodies just tend to separate ? [Hint : So long as the force applied does not produce the limiting frictional force the two will move with common acceleration. When the force applied exceeds that limiting value the block will move on the trolley with a different acceleration]

A hollow cylinder of radius R rotates about its axis which is vertical. A block remains in contact with the inner wall if the frequency of rotation is f hertz, but falls at lower frequaencies. The coefficient of friction between the block and the cylinder is
