Question

Q2 The standard section tables give the following dimensions for a 254x102x22 UB D- 254.0 mm, B- 101.6 mm,1-5.7 mm and T-6.8 mm where the symbols are defined in the diagram shown below 酀 (a) Calculate / for the section. -2771 cm (b) The tabulated value for l is 2841 cm, try to explain the discrepancy. (Hint you should have a look at the standard section tables for UBs The section properties for the beam shown were found in Q1. Find the largest bending moment that can be safely carried about xx if the maximum stress permitted is Q3 60 N/mm (15.2 kN m) 100 10
