Question

Question 3 (20 pts) R10-9. The state of strain at the point on the bracket has components $\epsilon_x = -130(10^{-6})$, $\epsilon_y = 280(10^{-6})$, $\gamma_{xy} = 75(10^{-6})$. 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.

The state of strain at the point on the bracket has
components
$\epsilon_x = -130(10^{-6})$, $\epsilon_y = 280(10^{-6})$,
$\gamma_{xy} = 75(10^{-6})$. 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.

Question 3 (20 pts)
R10-9.
The state of strain at the point on the bracket has
components
= -130(10^-6), = 280(10^-6),
γxy = 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.

R10-9. The state of strain at the point on the bracket has components as Îµx = 1280(10), Îµy = 7510. 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 xy plane.
