Question: An I - beam has a flange width b = 4 0 0 m m , height h = 4 0 0 m m ,

An I-beam has a flange width b=400mm, height h=400mm, web thickness tw=13mm, and flange thickness tf=21mm. Use the following steps to calculate the shear stress at a point 175mm above the neutral axis.
Part A - Moment of inertia
Part B - Q for the given point
The shear stress 175mm 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.
Part C - Shear stress
Use the results from Parts A and B to calculate the shear stress at a point 175mm above the neutral axis if the shear force on the section is V=8kN.
Express your answer with appropriate
units to three significant figures. I need help with part b and c plzzzz
An I - beam has a flange width b = 4 0 0 m m ,
