GPa] and has a cross sectional area of 520 mm?. Bar (2) is made of aluminium [E=70 GPa] and has a cross-sectional area of 960 mm?. After the load P is applied, the force in bar (2) is found to be 25 kN (in tension), Determine: the stresses in bars (1) and (2) the vertical deflection of point A. ) the load P. (d) Explain what is meant by a rigid bar and thedifference with deformable bodies.
