A uniform beam of mass m is inclined at an angle θ to the horizontal. Its upper end produces a ninety degree bend in a very rough rope tied to a wall, and its lower end rests on a rough floor (a) If the coefficient of static friction between beam and floor is μs determine an expression for the maximum mass M that can be suspended from the top before the beam slips. (b) Determine the magnitude of the reaction force at the floor and the magnitude of the force exerted by the beam on the rope at P in terms of m,M and μs

A uniform ladder of length L and mass m1 rests against a frictionless wall. The ladder makes an angle θ with the horizontal. (a) Find the horizontal and vertical forces the ground exerts on the base of the ladder when a fire fighter of mass m2 has climbed a distance x along the ladder from the bottom. (b) If the ladder is just on the verge of slipping when the fire fighter is a distance d along the ladder from the bottom, what is the coefficient of static friction between ladder and ground?

A uniform rectangular plate has side length l and 2l. The plate is in x−y plane with its centre at origin and sides parallel to x and y axes. The moment of inertia of the plate about an axis passing through a vertex (say A) perpendicular to the plane of the figure is I0. Now the axis is shifted parallel to itself so that moment of inertia about it still remains I0. Write the locus of point of intersection of the axis with xy plane
