Solved: The rectangular plate is subjected to the deformation shown by the das

Question

The rectangular plate is subjected to the deformation shown by the dashed line. Assume a = 600 mm, Ax = 1.1 mm, and Ay = 1.7 mm. Determine the shear strains Yxy and Yx'y' at point A. y Ax Ay 7 1 a * -x A a 1 1 Ay x - a Answers: Yxy = i µrad Yx'y' = i µrad Give the following problem a try. If you get stuck, here is one way to work it: Essential Solution Video. A rigid steel bar is supported by three rods as shown. There is no strain in the rods before the load P is applied. After load P is applied, the normal strain in rods (1) is 3890 um/m. Assume initial rod lengths of L1 = 1,250 mm and L2 = 2,000 mm. Determine the normal strain in rod (2).
