Important Questions on Rigid Body Dynamics: Part 1

Four point mass, each of mass are connected at a corner of a square of side by massless rods as shown in the figure, and axis are in the plane of the system and axis is perpendicular to the plane and passing through the centre of the square.

A force is applied on the plank such that the hollow hemispherical shell is in equilibrium as shown in the figure. The coefficient of friction is the same between the hemispherical shell and the plank as it is between the plank and the ground. Friction is just sufficient to prevent the slipping (Take and ). Then

A hexagonal body lies on a horizontal rough surface. A force acts on the side of a hexagonal body as shown in figure. Choose the correct option(s).

A rod, placed in vertical plane, is being pushed along a smooth horizontal surface by a horizontal force Mass per unit length of the rod is given where is distance from the action point of applied force and is the length of the rod. Then,
