A stepped bar with circular cross-section and supported at top, hangs vertically under its own weight. Dimensions of the bar are shown in the figure below. Calculate the elongation of the bar under its own weight. What is the change in diameter of the bar at section AA shown in the figure ? E= 2 x 10 N/mm2, density y = 8 x 10-5 N/mm² and Poisson's ratio m = 0.2. A 100 mm 70 mm -A + + ← 500 mm 500 mm 1000 mm
