1 The steel bar shown fig:1 has the following dimensions: - Total length 2400mm; 18 mm diameter for half the length and 12 mm diameter for the remaining half. (i) () (111) If the bar is subjected to a tensile force of 22.5kN, Calculate the normal stress and normal strain in the segment AB and BC respectively. Also find the total extension of the bar when it is subjected to a tensile force of 22.51N. What would be the extension of a steel bar of uniform diameter having the same length and same volume when subjected to the same tensile force?
