01 Figure 1 shows a rigid bar AB. pinned at A and loaded by at B by a force P. Two wires; Aluminium (CD) of length L, equal 0.4m and Magnesium (EF) of length L2 equal 0.3m, support the bar. The diameters are d, -4mm for CD and d₂=3mm for EF. Allowable stresses in Aluminium and Magnesium are o, = 200 MPa and 2 = 175 MPa, respectively. The corresponding Young's Moduli are; E. = 72 GPa and E₂ = 45 GPa. (a) Outline the conditions required to solve this problem (b) What is the maximum allowable load, P My Figure 1 Rigid Bar 12 (6+14)
