Q4. The triangular plate ABC is deformed into the shape shown by the dashed lines. If at A, EAB = 0.007, EAC = 0.015, and xy = 0.006 rad, determine the average normal strain along edge BC. 350 mm y A -Yxy 1 450 mm L B X (Note: Work show the SI units throughout the solution and the final result should be in SI units)

For the state of a plane strain with Ex, Ey and yxy components: (a) construct Mohr's circle and (b) determine the equivalent in-plane strains for an element oriented at an angle of 30° clockwise. Ex = 250 x 10-6 Ey = 310 x 10-6 Yxy = -100 × 10-6

2.20 please need help thank you

A differential element on the bracket is subjected to plane strain that has the following components: , Ex = 300 x 10-6, Ey = 200 x 10-6, Exy = -500 x 10-6. Use the strain-transformation equations and determine the normal strain Ex' in the x' direction on an element oriented at an angle of 60°. Note, a positive angle is counter clockwise.
