The belt is stretched over two identical pulleys of diameter meter. The initial tension in the belt throughout is 4N when the pulleys are at rest. In using these pulleys and belt to transmit torque, it is found that the increase in tension on one side is equal to the decrease on the other side. Find the maximum torque that can be transmitted by the belt drive given that the coefficient of friction between the belt and pulley is 0.30.

A conveyer belt is used to transfer granular material and the frictional resistance on the top of the belt is $F=500 \mathrm{N}$. Determine the smallest stretch of the spring attached to the moveable axle of the idle pulley $B$ so that the belt does not slip at the drive pulley $A$ when the torque $\mathbf{M}$ is applied. What minimum torque $\mathbf{M}$ is required to keep the belt moving? The coefficient of static friction between the belt and the wheel at $A$ is $\mu_{s}=0.2$
