Find the change in length, width, thickness and volume of the bar. Take E = 200 GN/m? and Poisson's ratio = 0.32. ôt = 0.0027 mm (decrease), ôV = 45.36 mm' (increase)] 7 A rectangular block 250 mm x 100 mm x 80 mm is subjected to axial loads as follows : 480 kN (tensile) in the direction of its length. 900 kN (tensile) on the 250 mm x 80 mm faces. 1000 kN (compressive) on the 250 mm x 100 mm faces. Taking E = 200 GN/m2 and Poisson's ratio as 0.25 find the following : (i) Change in volume of the block. (ii) Values of the modulus of rigidity and bulk modulus for material of the block. A bar of 30 mm diameter is subjected to a pull of 60 kN. The measured extension on gauge length of 200 mm is 0.09 mm and the change in diameter is 0.0039 mm.
