Shear Stress from Shear Load in closed non symmetric section Q t1 t2 Shear load is applied such that (pure) bending occurs can't use symmetry to determine where to start s = 0 arc length parameter approach: divide into two problems and superpose: Q t1 t2 = q* + q* is the shear flow we have developed to date opening the section and q1 is a constant shear flow in the closed section superposition => we add the two flows for the actual shear flow how do we calculate each. i.e q = q* + q1 We have one condition; the net has to match the applied load the second comes from the physical situation; the slip at the cut must be 0 q1 1/7
