2. A steel cable with a nominal diameter of 24 mm is used in a construction yard to lift a bridge section weighing 38 kN, as shown in the figure. The cable has an effective modulus of elasticity in the tre E 140 GPa. (a) If the cable is 14 m long, how much will it stretch when the load is picked up? (b) If the cable is rated for a maximum load of 70 KN, what is the factor of safety with respect to failure of the cable?
