Question

. A rotating shaft carries four masses A, B, C, & D which are radically attached to it. The mass centers are 30mm, 38 mm, 40 mm & 35 mm respectively from the axis of rotation. The masses A, C & D are 7.5 kg, 5kg, and 4kg respectively. The axial distances between the planes of rotation of A & B is 400mm & between B & C are 500mm.The masses A& C are at right angle to each other. Find for a complete balance (i) The angles between the masses B & D from mass A, (ii) The axial distances between the planes of rotation of C & D, and (iii) The magnitude of mass B

Answer 1

Answer:

i angle between b and d =50°

ii axial distance=45m

iii mass of b=5.5kg
