In the figure shown, the tension in Block B lying on a table weighs W. The coefficient of static friction between the block and the table is μ. Assume that the cord between B and the knot is horizontal. The maximum weight of the block A for which the system will be stationary is: the horizontal cord is 30 N. The weight of the body B is

A cube of side a and mass M is pivoted on a horizontal axis such that it can rotate about one of tis edges. Initially it is held in the highest position and then released. Find horizontal and vertical components of reaction of pivot on the cube at the moment when the reaction toward the centre of the cube becomes zero. Given that M.I of the cube about its edge is equal to (2)/(3)Ma^(2).

In the figure shown, a solid sphere of mass ‘m’ and radius r is released from a height 6r to slide down a smooth surface. A plank of same mass ‘m’ touches the horizontal portion of the surface at the ground. The co-efficient of friction between the plank and the sphere is mu and that between the plank and the ground is mu//4. Find the work done by the friction force between the plank and the ground till the sphere starts pure rolling on the plank. Neglect the height of the plank.
