Q.2 A beam 5 meters long, supported ends carries point load of 140 kN, 60kN and 80 kN at distance 0.5 meters, 2.5 meters and 3.5 meters respectively from the left end.
Find the maximum S.F. and B.M. Draw S.F. and B.M diagrams.
Q.3 Determine the maximum stress and elongation of a bar 2m long and 25mm diameter when an axial pull of 501EN is applied suddenly on it. E = 200 GN/m2
Q.4 A rod tapers uniformly from 40 mm diameter to 20 mm diameter in a length of 400mm. If the rod is subjected to an axial load of 10000N, find the extension of the rod. E = 2 x 105 N/mm2.
