10-102. The state of strain at the point on the bracket has components Px = -130(10-6), Py = 280(10-6), gxy = 75(10-6). Use the strain-transformation equations to determine ( a) the in-plane principal strains and ( b) the maximum in-plane shear strain and average normal strain. In each case specify the orientation of the element and show how the strains deform the element within the x - y plane. | |
