1.It is less than 8,000 N and greater than zero.
2.It is exactly 8,000 N.
3.It is greater than 8,000 N.
4.It is zero.

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.
