KHw Ch07_01 The Shear Formula Learning Goal: To calculate the shear stress at a point in the web of an I-beam section subjected to a shear force. When a beam section is subjected to a shear load, a Figure < 1 of 1 35 1 of 7 Review An I-beam has a flange width b = 200 mm, height h = 200 mm, web thickness tw = 8 mm, and flange thickness tf = 12 mm. Use the following steps to calculate the shear stress at a point 55 mm above the neutral axis. tf tw h Part A - Moment of inertia The shear formula includes the moment of inertia of the whole cross section, I, about the neutral axis. Calculate the moment of inertia. ? Part A - Moment of inertia The shear formula includes the moment of inertia of the whole cross section, I, about the neutral axis. Calculate the moment of inertia. Express your answer with appropriate units to three significant figures. ? View Available Hint(s) ?A ? I = Value Units Submit Part B - Q for the given point The shear stress 55 mm above the neutral axis depends on the value of Q for the area above that point. Calculate the value of Q. Express your answer with appropriate units to three significant figures. ? View Available Hint(s) ?A ? Q= Value Units Submit Part C Shoar stross 21 ? Review Part C - Shear stress Use the results from Parts A and B to calculate the shear stress at a point 55 mm above the neutral axis if the shear force on the section is V = 5 kN Express your answer with appropriate units to three significant figures. ?
