1 A steel bar is 40 mm in diameter for a length of 100 mm, 30 mm in diameter for a length of 60 mm and 20 mm in diameter for the remaining 80 mm of its length. Calculate the load required to produce a total elongation of 0,177 mm in the rod. What would be the diameters of a steel tube of the same total length and same material subjected to a load of 70 kN to produce the same elongation namely 0 177 mm Assume a
