The left-hand end of a slender uniform rod of mass m is placed against a vertical wall. The rod is held in a horizontal position by friction at the wall and by a light wire that runs from the right-hand end of the rod to a point on the wall above the rod. The wire makes an angle θ with the rod. a)What must the magnitude of the friction force be in order for the rod to remain at rest?...

A uniform rod of mass M and length 2l stands vertically on a
rough horizontal floor and is allowed to fall. Assuming that
slipping has not occured, evaluate the angular speed of the rod
when the rod makes an angle of theta with the vertical. if the
slipping occurs when the rod is at theta=30 degrees with respect to
vertical, calculate the value of the coefficient of static
friction.
