A brass nameplate is 2.00 cm x 10.0 cm x 30.0 cm in size. A force F of 4.0010^5N acts on the upper left side and the bottom right side, as shown in thefigure.

Determine the shear strain x/h, which relates to the amount x of horizontal deformation of the top edge and the vertical height hof the nameplate.

Determine the angle ofdeformation.

I tried to solve this practice problem, but I keep obtaining incorrect answers. I am not sure what I am doing wrong.
