Question No.15: Four masses M₁, M₂, M₃, and M₄ are 200kg, 300kg, 240kg and 260kg respectively. The
corresponding radii of rotation are 0.2m, 0.15m, 0.25m and 0.3m respectively and the angle between
successive masses45°, 75°, and 135°. Find the position and magnitude of balance mass required if its
radius of rotation is 0.25m.
