(a) A member ABC is formed by connecting a steel bar of 20mm diameter to an aluminium bar of 30 mm diameter, and is subjected to forces as shown in figure. Evaluate the total deformation of the bar, taking E for aluminium as 0.7 x 105 N/mm2 and that for steel as 2 x 105 N/mm2
(b) A circular rod of 12 mm diameter was tested for tension. The total elongation on a 300mm length was 0.22 mm under a tensile load of 17KN. Determine the value of E.
