A rectangular parallelepiped of mass m has three sides of length l,2l and 3l respectively. State with reason, in which position the block should be kept at rest on a horizontal floor so as to attain the highest stability of equilibrium.

A rectangular parallelepiped of mass m has three sides of length l,2l

1.	A rectangular parallelepiped of mass m has three sides of length l,2l and 3l respectively. State with reason, in which position the block should be kept at rest on a horizontal floor so as to attain the highest stability of equilibrium.
Answer» Solution :The longer sides` 2l` and `3l` should FORM the horizontal base of the parallelepiped. In this position maximum STABILITY of equilibrium can be achieved. CENTRE of gravity is at its LOWEST possible position i.e., at a HEIGHT of `(l)/(2)` from the base and the base area is maximum.
