A rectangular beam 6 in. wide by 10 in. high supports a total distributed load of W and a concentrated load of 2W applied as shown in Fig. P-583. If fb ≤ 1500 psi and fv ≤ 120 psi, determine the maximum value of W.
Based on allowable bending stress:
Based on allowable shearing stress:
For safe value of W, use W = 2 222.22 lb. answer
