A block of weight W is placed on a wedge and arranged as shown in fig. find the force F needed to hold the cart equilibrium if there is no friction.

If the tension T needed to hold the cart equilibrium is (sqrt3W)/(x) there is no friction. Find value of x .

Two identical blocks of weigth w are placed one on top of the other as shown in figure. The upper block is tied to the wall. The coefficient of static friction between B and ground is mu and friction between A and B is absent. When F=mu w force is applied on the lower block as shown. The tension in the string will be

A block weighing w is held against a vertical wall be pressing horizontally with a force F. Then, F needed to hold the block is

Find the acceleration of rod A and wedge B in the arrangement shown in fig if the ratio of the mass of wedge to that of the rod equals eta and the friction between the contact surfaces are negligible.
