Just a few questions. 1). A bar of 2m and diameter 40mm, is subjected to an axial tensile force of 50KN. What will be the elongation and the reduction in diameter. The aluminium bar has a Modulus of Elasticity E = 70 Gpa and a poissons ratio v = 0.3 2). A 1.5m steel bar has a cross sectional area of 100mm x 50mm. If a force of 120KN is applied what will be the longitudial and lateral strain, and the change in dimension. Assume that for steel E = 200Gpa and v = 0.3.
