(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?

Solve the problem below. For your final answer, use whole number. An extra flexible 8 × 19 steel wire rope of 38 mm diameter is used with a 2 m diameter hoist drum to lift 70 kN of load. The wire rope has a length of 900 meters. The maximum speed is 3 m / s and the acceleration is 1.5 m / s2. The diameter of the wire may be taken as 0.05 d, where d is the diameter of wire rope.
