A"V" shaped rigid body has two identical uniform arms. What must be the angle between the two arms so that when the body is hung from one end, the other arm is horizontal ?

A rigid body in the shape of a "V" has two equal arms made of uniform rods. What must the angle between the two rods be so that when the body is suspended from one end, the other arm is horizontal ?

The angle between two arms of a letter ‘L’.

A rigid body is made of three identical thin rods, each with length fastened together in the form. of letter H . The body is free to rotate about a horizontal axis that runs along the length of one of the arms of H . The body is allowed to fall from rest from a position in which the plane of the H is horizontal. What is the angular speed of the body when the plane of H is vertical?

The arms of a vertical U tube of uniform inner cross section contains mercury. In one of the arms of the tube, water column of length 8 cm is introduced. In the other arm, oil of density 0.75 g/cm ""^(3) is poured till the upper surfaces of water and oil are at same horizontal level. Calculate the length of oilcolumn.
