Drums of oil are carried in a truck. If a constant accleration is applied on the turck, the surface of the drum will-

In a machine, a block continously slides forward and backward on a horizontal platform. When lubricating oil is applied to their surfaces n contact, then the friction between them

A block of mass 2kg is kept on a truck moving with a constant acceleration. The height 'h' of the block is 60 cm and its width 'w' is 15 cm . The surface between the block and the truck is sufficiently rough toprevent slipping. The minimum acceleration of the truck at which the topple is (take g = 10 m//s^(2) )

Three identical cubes each of mass m are place on a smooth horizontal surface.A constant force F is applied on A as shown in the figure.The force on B applied by C is

A block of mass 1kg lies on a horizontal surface in a turck, the coefficient of static fricition between the block and the surface is 0.6, what is the force of fricition on the block. If the acceleration of the truck is 5m//s^(2) .

Why are lubricants (oil or greses) applied to rubbing surface of machines ?

A body kept on a smooth horizontal surface is pulled by a constant horizontal force applied at the top point of the body. If the body rolls purely on the surface, its shape can be-

A cylinder is kept at rest on a sufficiently rough horizontal surface. A horizontal constant force is applied at the centre of mass of cylinder.
