For Certain Values Of W And P The Maximum Positive Bending Moment In The Beam Is 8870 Lb Ft And The Maximum Negative 1 (39.99 KiB) Viewed 21 times

For certain values of w and P, the maximum positive bending moment in the beam is +8870 lb-ft, and the maximum negative bending moment is -10772 lb-ft. The cross section of the beam is shown. The pertinent section properties of the cross section are e = 3.70 in., f = 2.10 in., and I₂ = 13.3847 in.4. Calculate (a) the maximum tensile bending stress and (b) the maximum compressive bending stress that is produced in the beam. Enter your answers with the appropriate sign. A a W d B b P с e D
