INFO:
Beam AB shown below experiences a pure bending loading M. This beam is made up of two planks, each of thickness t, joined together to create a T-shaped cross section.(a) Determine the distance C that determines the location of the neutral axis of the beam.(b) Determine the normal stress at location a on the cross section of the beam.(c) Determine the normal stress at location b on the cross section of the beam.Use the following: M = 15 kip·ft, D = 4 in, H = 6 in, and t = 2 in.
