B: Answer the following questions. 1. Calculate the elongation of the cable due to load, if a steel cable of 4em diameter is used to lift a load of 350kg. Given that and the length of cable is 10m and E-3x10'kg/em. 2. A tensile test was conducted on mild steel bar. The load at elastic limit was 200KN and the diameter of the steel bar was 3em. What will be the value of stress? 3. A steel bar 600mm long and having 30mm diameter, is turned down to 25mm diameter for one fourth of its length, It is heated at 30 C above room temperature, clamped at both ends and then allowed to cool to room temperature. If the distance between the clamps is unchanged, the maximum stress in the bar ( a = 12.5 x 10* per C and E = 200 GN/m) is 4. Determine the yield stress of a steel rod 15 mm diameter, if the yield load on the steel rod is 70KN. 5. Where do the maximum BM occurs for the below diagram. 10 KN
