It will be noticed that when a body is in a position of stable equi-librium, a disturbance by tilting has the effect of raising the centre + W … |R(a) FlO. 132.—Stability of a block on an inclined plane. of gravity. Further, if a body is capable of moving under the actionof gravitational effort, it will always move in such a way as to bringthe centre of gravity into a lower position. A position of stableequilibrium will be attained when (as…
