Unformatted text preview: s max occur? What is the magnitude s max of the maximum bending stress? What is the ratio of the maximum stress to the largest stress s B at the support? (b) Repeat (a) if, in addition to P and M , a triangular distributed load with peak intensity q ± 3 P / L acts upward over the entire beam as shown. What is the ratio of the maximum stress to the stress at the location of maximum moment? (a) h A = 2.0 in. h B = 3.0 in. B A b = 1.0 in. b = 1.0 in. x P = 50 lb M = 800 lb-in. L = 20 in. (b) B A x P = 50 lb M = 800 lb-in. L = 20 in. 3 P L — q = 05Ch05.qxd 9/24/08 4:59 AM Page 434...
