The state of strain at the point on the leaf of the caster assembly is shown in Figure 1. Use the strain transformation equations to determine the equivalent in-plane strains on an element oriented at an angle of 0=30 counterclockwise from the original position. Ex=-404 10 -6 Ey = -406 x 10-6 z=-406 10-6 Also, use the strain-transformation equations to determine the following: -The in-plane principal strains. - Maximum in-plane shear strain. - Average normal strain. - Explain the significance of the calculated values.
