Problem 1: Consider the idealized closed section shown which carries a shear force of 8000 lb at the location shown. Determine the shear flows in the webs of the idealized beam shown for the following two cases. (a) All stringers have an area of 1 in². (b) The two right hand side stringers have an area of 3 in² and all other stringers have an area of 1 in². An alternative solution path to solve for the shear flows is as follows. It is possible to find the shear flows by the superposition of the shear flow values obtained by (i) assuming one of the webs in the section to be cut, and (ii) the uniform shear flow along the entire circumference of the closed section (see the figure below). Then, by equating the moments from both (i) and (ii) to the moment due to the shear force Vy, the value of qo can be evaluated. Using this alternative method, solve for the shear flows for the following case: A (c) The two left hand side stringers have an area of 3 in² and all other stringers have an area of 1 in². Alternate solution path: F 10" qAB qEF B E 10 -- qBC qCD DE K-6" 8,000 lb (i) Calculate the shear flow due to the applied shear force Vy of the open section (considering one of the webs to be cut).
