A clutch was balanced by having four masses placed on the clutch cover at the same radius. Three of the masses are 40 g, 50 g, and 25 g respectively, and their angular positions from the vertical, in a clockwise direction, are 00, 1200 and 2100 respectively. Assuming that radial force is proportional to the mass, find, by applying the polygon of forces rule, the magnitude and position of the fourth mass. Use scale of 10 mm = 5 g.
