b) If a pipe with an inner diameter of 36 mm is subjected to an axial load of 5.20 x 105 N and the maximum allowable stress in the pipe is 7.5 x 109 N/m², calculate the minimum wall thickness required for the pipe. Give your answer in millimetres (mm) to 2 decimal places. [7 marks] c) A wire with a Young's Modulus, E, of 8.5 x 106 N/m² and an original length of 1.5 m is under tension. If the wire length extension is 2.5 mm, calculate the stress in the wire. Give your answer in N/m² to 2 decimal places. [6 marks]
