The inverted track T with freely floating cylinder C compris

The inverted track T with freely floating cylinder C comprise a system which is designed to hold paper or other thin materials P in place. The coefficient of static friction is mu for all interfaces. What minimum value of mu ensures that the device will work no matter how heavy the supported material P is?

Solution

Answer of the following given problem is as follows.

The static friction coefficient for the given inverted track is .0345
