Q3. A hanging platform has four cylindrical supporting cables of diameter 2.5 cm. The supports are made from solid aluminium, which has a Young's Modulus of Y = 69 GPa. The weight of any object placed on the platform is equally distributed to all four cables. a) When a heavy object is placed on the platform, the cables are extended in length by 0.4%. Find the mass of this object. (3) b) Poisson's Ratio for aluminium is v= 0.33. Calculate the new diameter of the cables when supporting this heavy object. (3) (6 marks)
