Question

please solve the question clearly and put the graph in different paper and make numbers for the parts of question.and your font don’t mixed.?

b) Every student is assigned with separate problem. Student need to solve the required calculation A shaft carries four masses A, B, C and D of different magnitude and revolving at radii as mentioned below 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. If the balancing masses revolve at a radius of 250 mm, find their magnitudes and angular positions graphically. i. The magnitude of mass X and Y (02 marks) ii. The angular position of mass X and Y. (02 marks) iii. Draw Space diagram. (02 marks) iv. Couple Polygon (04 marks) v. Force Polygon (04 marks) vi. Tabular Column (06 marks) AMUR AL Ma=250kg, Mb=300kg, Mc= 400kg, Md= 250kg, Ra= 0.15m Rb= 0.2m Rc= 0.25m Rd= 0.2m
