The rectangular bar shown below is 1.5 meters long, and is pulled in tension by an 80kN force. The materials elastic modulus (E) is 10000MPA, and the Poisson's ratio is 0.2. Assume the yield stress of the steel is 50MPA. a. Determine the change in length of the bar. b. Determine the axial stress in the bar. c. Calculate the axial strain and the lateral strain for the bar. d. The bars cross sectional dimensions was 50mmx100mm before the 80kN load was applied. What are the new cross sectional dimensions after the load is applied? e. What is the factor of safety for the bar? P=80 kN 50 mm 1.5 m P= 80 kN 100 mm
