Step 1
First, we need to determine the moment of inertia (I) of the beam. The moment of inertia is a measure of how resistant an object is to changes in its rotational motion. In this case, we need to find the moment of inertia about the neutral axis of the beam. Show more…

A copper (shear modulus 4.2 x 10^10 N/m^2) cube, 0.325 m on a side, is subjected to two shearing forces, each of magnitude F = 7.83 x 10^6 N (see the drawing). Find the angle θ (in degrees), which is one measure of how the shape of the block has been altered by shear deformation.
