A cubical block is experiencing three forces `F_(1) = 20 N` acts at angle `45^(@)`with horizontal and lies in diagram plane of the cube `F_(2) = 30 N` acts along y- axis and `F_(3) = 40 N` acts in x- direction as shown in fig find the friction force acting on the block if it is at rest

If in pervious problem, an additional force F' = 100N is applied in vertical direction as shown in figure The friction force acting on the block is

Calculate F such that frictional force acting on all blocks zero.

A block of mass 20 kg is acted upon by a force F=30N at an angle 53^@ with horizontal in downward direction as shown. The coefficient of friction between the block and the forizontal surface is 0.2 . The friction force acting on the block by the ground is (g=10(m)/(s^2) )

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.

Two thin roads are moving perpendicularly as shown in the figure. If the friction acting between them is F_(R ) then the unit vector in the direction of friction force acting on the rod lying along x-axis is
