Calculate the elongation of the cable due to load, if a steel cable of 4cm diameter is used to lift a load of 350kg. Given that and the length of cable is 10m and E=3x10 kg/cm. A tensile test was conducted on mild steel bar. The load at elastic limit was 200KN and the diameter of the steel bar was 3cm. What will be the value of stress?
