A square steel plate is 9.00 cm on a side and 0.600 cm thick. Assume that the plate is oriented with the square faces horizontal to the ground.
A. Find the shear strain that results if a force of magnitude 1.00×106 N is applied to the top square face of the plate, parallel to the side, and a force of equal magnitude is applied in the opposite direction to the bottom face of the plate as shown .
Note that the shear modulus of steel in pascals is 7.50×1010 Pa.
B. Find the displacement Delta x in centimeters.
help on this plz
