Question:

A pulley is driven by a belt as shown in the figure below. Neglecting centrifugal effects the minimum coefficient of friction that will prevent slipping between the belt and the pulley is most nearly:

Frictional Force:

It the force resisting the motion of a body when certain force is applied to that. The frictional force always acts in the opposite direction of the motion of the body.

Frictional force is the product of the coefficient of friction and the normal reaction (N).

{eq}F=\mu N {/eq}

The driving tension ratio is given by,

{eq}\dfrac {T_1}{T_2}=e^{\mu \theta } {/eq}

Where, {eq}T_1 {/eq} and {eq}T_2 {/eq} are the tensions...
