(a) A steel cable with nominal diameter 25 mm as shown in Table Q2(a) is used in a construction yard to lift a bridge section weighing 38 kN, as shown in Figure Q2(a). The cable has an effective modulus of elasticity E = 140 GPa. (i) If the cable is 14 m long, how much will it stretch when the load is picked up? (ii) 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?
