The strain components for a point in a body subjected to plane strain are &x=930 μE, &y=-1120μe and Yxy = -583 μrad. Using Mohr's circle, determine the principal strains (Ep1₁ > Ep2), the maximum inplane shear strain Yip, and the absolute maximum shear strain Ymax at the point. Show the angle 8, (counterclockwise is positive, clockwise is negative), the principal strain deformations, and the maximum in-plane shear strain distortion in a sketch. Answers: Ep1 = με. Ep2 = με. Vip= urad. Ymax= Өр- 0 urad.

Consider a point in a structural member that is subjected to plane stress. Normal and shear stress magnitudes acting on horizontal and vertical planes at the point are Sx = 17 ksi, Sy = 24 ksi, and Sxy= 16 ksi. (a) Determine the principal stresses (1 > 2) and the maximum in-plane shear stress Tmax acting at the point. (b) Find the smallest rotation angle 0, (counterclockwise is positive, clockwise is negative) that will rotate to principal directions. Then show these stresses in an appropriate sketch (e.g., see Figure 12.15 or Figure 12.16) Answers: Opl = Op2 = Tmax = Sxy 0 ksi. ksi. ksi.

The strain components εx, εy, and γxy are given for a point in a body subjected to plane strain. Determine the principal strains, the maximum in-plane shear strain, and the absolute maximum shear strain at the point. Show the angle θp, the principal strain deformations, and the maximum in-plane shear strain distortion on a sketch. εx = -850 με, εy = -255 με, and γxy = 1100 μrad. Enter the angle such that -45°≤θp≤ +45°.
