Q13 For the beam section shown in Figure Q13, the structure has been idealised into booms (B1-B5) which carry all the direct stresses and thin web sections between which only resist shear forces. The section is symmetrical about the y axis. 6a B4 B3 ******************** ба S₂ a Your tasks are: a) To find the maximum shear stress in the section b) To find the rate of twist of the section B5 ************** B2 4a ********** B1 Figure Q13 The areas of the booms are as follows: B1 = 2500 mm² B2 = B5 = 4000 mm² B3 = B4 = 1cd0 mm² where c and d are the last two digits of your student number. As an example, if your student number is 965337, then the areas of B3 and B4 would be 1370 mm². The thickness of all the webs is constant at 2.0 mm; the value of a is 80 mm and the shear modulus is constant at G = 40,000 N/mm² A shear force S₂ = 160 kN is applied a distance a to the left of B5 as shown above.
