Question 1 (10 marks) Two cables, AC and BC, are used to hold the weight of mass m = 1,000 kg, as shown in Figure Q1 below. Both cables are of the same length and diameter and are made from the same material. Masses of both cables are ignored. (a) What is the load in cable AC? (3 marks) (b) If cable AC and BC are made from steel with a Young's modulus of 210 GPa, and has diameter of 15 mm, how far does each stretch when supporting the mass m? ( 4 marks) (c) What is the total strain energy contained in both cables when supporting the mass m? (3 marks) 0.8 m- 0.8 m- A B 1.6 m m Figure Q1
