A cantilever beam AB is loaded by a coupleat its free end (see fgure). The length of the beamis L=2.0 m , and the longitudinal normal strain at the top surface is=0.0010 . The distance from the top surface of the beam to the neutral surface is c =85 mm . (a) Calculate the radius of curvature, the curvature, and the vertical deflectionat the end of the beam. (b) If allowable strain=0.0008 , what is the maximum acceptable depth of the beam? [Assume that the curvature is unchanged from part(a)]. (c) If allowable strain= 0.0008 , c = 85 mm , and L= 4 m , what is deflection?
