Question

A 25 mm diameter bar when subjected to a force of 40 kN has an extension of 0.08 mm on guage length of 200 mm. If the diametrical reduction is 0.003 mm, find the values of E, G, K, poisson’s ratio.​

Answer 1

Answer:

Data: d=30 mm, L=200 mm, P =60 kN, δL=0.09 mm, δd = 0.0039 mm Calculate: μ and EA=πd24=π×3024=706.858mm2E=PLAδL=60×103×200706.858×0.09=188628.0
