A shaft carries four masses a, b, c and d of magnitude 200 kg, 300 kg, 400 kg and 200 kg respectively and revolving 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. The balancing masses are to be placed in planes x and y. The distance between the planes a and x is 100 mm, between x and y is 400 mm and between y and d is 200 mm. If the balancing masses revolve at a radius of 100 mm, find their magnitudes and angular positions.
