I-beam has a flange width b = 400 mm , height hℎ = 400 mm , web thickness tw = 13 mm , and flange thickness tf = 21 mm . Use the following steps to calculate the shear flow at the point shown, where x = 55 mm . A) The formula for the shear flow includes the moment of inertia of the whole cross section, I, about the neutral axis. Calculate the moment of inertia. B) The shear flow at the point depends on the value of Q for the portion of the upper flange to the right of the point. Calculate the value of Q C) Use the results from Parts A and B to calcu
