When an axial load is applied to the ends of the bar shown, where L₁ = 30 in. and L₂ = 80 in., the total elongation of the bar between joints A and C is 0.100 in. In segment (1), the normal strain is measured as 1700 pin./in. Determine the normal strain in segment (2) of the bar. A L₁ B L2

The strain components Ex, Ey, and Yxy are given for a point in a body subjected to plane strain. Using Mohr's circle, determine the principal strains, the maximum in-plane shear strain, and the absolute maximum shear strain at the point. Show the angle 0p, the principal strain deformations, and the maximum in-plane shear strain distortion in a sketch. Ex = 0 μE, Ey = 310 με, Yxy = 280 μrad. Enter the angle such that -45° ≤ 0,≤ +45° Answer: Ep1 = Ep2 = Ymax in-plane = Yabsolute max. = 0p = με με urad urad

The bar has a length of 8 in. and a square cross-sectional 5000 lb 5000 lb area of 0.5 in. x 0.5 in. It is made of a material having the stress-strain diagram shown. If the bar is subjected to an 8 in. σ (ksi) axial force of 5000 lb, determine 75 (a) the change in the 8-in. length, 60 (b) the change in the 0.5-in. thickness. 45 Assume Poisson's ratio is 0.30. 30 15 € (in./in.) 0.001 0.002 0.003 0.004 0.005 0.006 0.007
