Question:

A cantilever beam AB is loaded by a couple Mo at its free end (see figure.) The length of the beam is L = 15 and the longitudinal normal strain at the top surface is 0.001. The distance from the top surface of the beam to the neutral surface is 75 mm.
Calculate the radius of curvature (, the curvature k, and the vertical deflection Î´ at the end of the beam.
