As the system is in equilibrium, the tension in the string is given by
T=Mg
Now we will calculate the horizantal and vertical force seperately
Total vertical forces acting on the pulley is
=mg+T(mg is due the mass of the pulley and T is due to tension in the string, both forces acting vertically downwards )
= mg+Mg
 Total horizontal force acting on the pulley is T or Mg( as T=Mg) acting awar from the clamp
Now these two forces are perpendicular to each other and hence the resultant is given by
square root of open parentheses m g plus M g close parentheses squared plus open parentheses M g close parentheses squared end root
Hence the force by the clamp on the pulley is square root of open parentheses m g plus M g close parentheses squared plus open parentheses M g close parentheses squared end root.

A piece of wire is bent in the shape of a parabola y = kx^2 with a bead of mass m on it. The bead can slide on the wire without friction. It says at the point of the parabola when the wire is at rest. The wire is now accelerated parallel to the x axis with a constant acceleration a. The distance of the new equilibrium position of the bead , where the bead can stay at rest with respect to the wire from y axis is

if two boxes are kept over one another and an external force is applied on the lower box such that both the boxes move with same acceleration then will there be any friction acting between the both boxes???
