A cantilever beam of rectangular cross section is subjected to a concentrated load P = 17 k acting at the free end (see figure). The beam has width b = 3 in. and height h = 12 in. Point A is located at distance c = 2.5 ft from the free end and distance d = 9 in. from the bottom of the beam.
Calculate the principal stresses (1 and (2 and the maximum shear stress tmax at point A. Show these stresses on sketches of properly oriented elements?
