A double tee cross section is used for the beam shown below. Assume the following lengths and loads:
a=13ft
b=7ft
c=10ft
P=11500lb
=4000lbThe moment of inertia of the cross section is
I_(z)=110in.^(4). Determine the magnitude (i.e., the absolute value) of the maximum tensile bending stress in the beam. Answer: Tension
