Solve Problem on Balancing of masses rotating in different planes by using graphical method.
A shaft carries four masses A, B, C and D of magnitude 200 kg, 300 kg, 400 kg and 200 kg respectively at radii 80 mm, 70 mm, 60 mm and 80 mm in planes measured from A at 300 mm, 400 mm and 700 mm. The angles between the cranks measured anticlockwise are A to B 45°, B to C 70°and C to D 120°. Balancing masses are to be in planes X and Y. Distance between planes A and X is 100 mm, between X and Y is 400 mm and between Y and D is 200 mm. If balancing masses revolve at radius of 100 mm, find their magnitude and angular positions.
