Section-B
Q2. Attempt any five parts (5×10=50)
- (a) Three smooth spheres of weight 'P', 'P', 'Q' are placed in a smooth trench as shown in fig. find the support reactions at point of contact A,B,C,D. The following numerical data are given: P=300N, Q = 600N, r1 = 400mm, r2 = 600mm, r3 = 400mm and a = 30°.
- (b) Two blocks of weights W1 and W2 rest on rough inclined plane and connected by a short piece of string as shown in fig. If coefficient of friction are 0.2 for blockl and 0.3 for block 2 respectively, find the angle of inclination of plane for which sliding will impend. Assume W1=W2=225N
