Q.5(a) Find the position of the centroid of a quadrant of an elliptic lamina. 9 (b) Two bodies, weights W, W2, are placed on an inclined plane and are connected by a light string which coincides with a line of greatest slope of the plane. If the coefficients of friction between the bodies and the plane be respectively , and . Find the inclination of the plane to the horizon when both bodies arc on the point of motion, it being assumed that the smoother body is below the other.
