Find the tension to hold the car equilibrium, if there is no friction.

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 .

A block is placed on a rough horizontal plane. Three horizontalforces are applied on the block as shown in the figure. If the block is in equilibrium, find the friction force acting on the block.

A wire frame ABCD has a soap film. The wire BC can slide on the frame without friction and it is in equilibrium in the position shown in the figure. Find m, if T is the surface tension of the liquid.

U - shaped film of a liquid is formed between a wire frame and movable wire 5 cm long. Then the force required to hold the wire in equilibrium is , (Surface tension of liquid is 0.024 N/m )

A ball of mass M is in equilibrium between a vertical wall and the inclined surface of a wedge. The inclination of the wedge is theta = 45^(@) and its mass is very small compared to that of the ball. The coefficient of friction between the wedge and the floor is mu and there is no friction elsewhere. Find minimum value of mu for which this equilibrium is possible

A simple pendulum of length l and bob of mass m is displaced from its equilibrium position O to a position P so that hight of P above O is h . If is then released. What is the tension in the string when the bob passes through the through the equilibrium position O ? Neglect friction. v is the velocity of the bob at O

Block A in figure weights 90 N. The coefficient of static friction between the block and the surface on which it rests is 0.3. The weight w is 15N, and the system is in equilibrium. Find the friction force exerted on block A.(b) Find the maximum weight w for which the system will remain in equilibrium.
