Question 5.6-7

uut be used in od is axis bending (i.e., it must bend about the 2-2 (or y) axis of the cross section). weak (a) Ift 5.6-7 A simple beam A figure (a) Calculate the required section modulus S if (b) R th 5.6-9 Onllow = 124 MPa, L = 9.75 m, P-13 kN, and wooo q = 6.6 kN/m. Then select a suitable I-beam (IPN shape) from Table F-2, Appendix F, and tert recalculate S taking into account the weight of joist the beam. Select a new beam size if necessary. the joist gow beam size if necessary. The (b) What is the maximum load P that can be applied to your final beam selection in part (a)? an PROBLEM 5.6-7
