Please solve quickly B: Answer the following questions.1. Calculate the elongation of the cable due to load, if a steel cable of 4cmdiameter is used to lift a load of 350kg. Given that and the length of cable is10m and E-3x10'kg/cm.2. A tensile test was conducted on mild steel bar. The load at elastic limit was200kN and the diameter of the steel bar was 3cm. What will be the value ofstress?3. A steel bar 600mm long and having 30mm diameter, is turned down to 25mmdiameter for one fourth of its length. It is heated at 30 C above roomtemperature, clamped at both ends and then allowed to cool to roomtemperature. If the distance between the clamps is unchanged, the maximumstress in the bar ( a = 12.5 x 10 per C and E = 200 GN/m) is4. Determine the yield stress of a steel rod 15 mm diameter, if the yield load onthe steel rod is 70kN.5. Where do the maximum BM occurs for the below diagram.10 KNA2M3M
