Two blocks of mass 'm' and 'M, are connect to the ends of a string passing over a pulley. 'M' lies on the plane inclined at an angle theta with the horizontal and 'm' is hanging vertically as shown in Fig. The coefficient of static friction between 'M' and the incline is mu_(s) . Find the minimum and maximum value of 'm' so that the system is at rest.

A mass m rests under the action of a force F as shown in the figure-2.158 on a horizontal surface. The coefficient of friction between the mass and the surface is mu . The force of friction between the mass and the surface is :

The coefficient of friction between m_(2) and inclined plane is mu (shown in the figure). If (m_(1))/(m_(2))=sin theta then

The coefficient of friction between m_(2) and inclined plane is mu (shown in the figure). If (m_(1))/(m_(2))=sin theta then

In the arrangement shown in figure the cylinder of mass M is at rest on an incline. The string between the cylinder and the pulley (P) is horizontal. Find the minimum coefficient of friction between the incline and the cylinder which can keep the system in equilibrium. Also find the mass of the block. Assume no friction between the pulley (P) and the string.

A block of mass M is placed on a rough horizontal surface. It is connected by means of a light inextensible string passing over a smooth pulley . The other end of string is connected to a block of mass m. There is no friction between vertical surface and block m The minimum value of coefficient of friction mu such that system remains at rest , is
