Question
A simple beam AB is loaded as shown in the figure. A В L L L 4 4 4 4 (a) Calculate the required section modulus S (in in.³) if oallow 18,000 psi, L = 15 ft, P = 3,250 lb, and q = 450 lb/ft. (At this point, disregard the weight of the beam.) 0.85286 X in. 3 Select a suitable I-beam (S shape) from this table, and recalculate S (in in.3), taking into account the weight of the beam. Select a new beam size if necessary. (Select the most economical beam size for your calculations.) 1.000 in. 3 What is the suitable beam size? O S6x 12.5 O S6x 17.2 O S 8× 23 O S 10 x 25.4 OS 8× 18.4 (b) What is the maximum load P that can be applied to your final beam selection in part (a)? (Enter the magnitude in Ib.) 3221 X Ib
