The beam in Problem 7.23 is made of yellow pine for which E = 12.0 GPa. Determine the deflection at the center of the beam.

Problem 7.23

A simple beam is subjected to a concentrated load P = 4.00 kN at the midlength of a span of 2.00 m. The beam cross section is formed by nailing together two 50 mm by 150 mm boards as indicated in Figure P7.23. The plane of the loads passes through the centroid of the cross section as indicated. Determine the maximum flexure stress in the beam and the orientation of the neutral axis.
