Question 2A rigid bar of weight W=1,200 N hangs from three equally spaced vertical wires as shown in Figure Q2.The wires also support a concentrated load P acting on the bar. The diameter of the steel wires is 6 mm whilethe diameter of the aluminium wire is 15 mm. Assume the modulus of elasticity of steel and aluminium areE, 200 x 103 N/mm² and Ea = 80 x 103 N/mm² respectively.(a) Set up the equilibrium and compatibility equations for the system shown.[7 marks](b) What load Pallow can be supported at mid-span of the bar if the allowable stress in the steel wire is 210N/mm² and that in the aluminium wires is 70 N/mm². You are expected to show all calculations orchecks for both aluminium and steel wires.[15 marks](c) What will be the change in length of each wire when the load Pallow is acting?[3 marks]A950 mmSAS = Steel250 mm250 mmA Aluminium→WFigure Q2

A bridge truss extends x = 206 m across a river (shown in the figure below) where 8 = 39º. The structure is free to slide horizontally to permit thermal expansion. The structural components are connected by pin joints, and the masses of the bars are small compared with the mass of a 1340 kg car at the center. Calculate the force of tension or compression in each structural component (in N).
