and y of the centre of gravityhave now been found. Example.—Apply the above method to find the centre of gravity of athin semicircular sheet (Fig. 136). The diameter AB is 5 inches. The centre of gravity of the sheet lies in OC, which is a radius drawnperpendicular to AB, hence y alone need be… … = 1-05 inches. Fig. 136.—Centre of gravity of a semicircularsheet. It is known that the centre of gravity of a semicircular sheet lies at adistance 4r37r from AB (Fig. 136). Using this expression in order tocheck the above result, we obtain _ 4x2-5 y 3x = 1-06 inches. 7T Positions of…
