A double tee cross section is used for the beam shown below. Assume the following lengths and loads: $a = 14$ ft $b = 7$ ft $c = 10$ ft $P = 8500$ lb $Q = 3000$ lb The moment of inertia of the cross section is $I_z = 110$ in.$^4$. Determine the magnitude (i.e., the absolute value) of the maximum tensile bending stress in the beam. Answer: $\sigma_{\text{max}}$ (Tension) = psi 3.2 in. 5.8 in.
