INSTRUCTION: This section consists of TWO (2) structured questions. Answer all question. QUESTION 1 a) Express the stress in copper bar of 30mm diameter if axial compression load of 60 kN is applied. b) A copper wire of 4m length was acting by 115 kN of tensile load. If the stress and Young Modulus applied is 72 MN/m² and 112 GN/m². calculate: i i. The strain of the copper wire The elongation of copper wire The diameter of copper wire iii. c) In a tensional test on mild steel rod of 13 mm diameter with 202 mm gauge length, the following observation were made: Extension under load of 17 kN=0.15 mm Load at yield point = 28.5 kN Ukimate load = 63 kN Diameter of wire = 7.66 mm Young modulus Yield stress Ultimate stress Percentage of reduction area Calculate: i iv.
