A simply supported wood beam of length l = 6 ft carries a concentrated load p at midspan, as shown. the cross-sectional dimensions of the beam are b = 6 in. and h = 11 in. if the allowable shear strength of the wood is 155 psi, determine the maximum load p that may be applied at midspan. neglect the effects of the beam's self-weight.
