A W6x9, A992 steel beam is cantilevered out 10 feet and has a variable distributed load that goes from 200 lb/in to 0 lb/in over the 10 feet length. The beam is oriented as shown.

·         Draw the LOAD, SHEAR, and MOMENT diagrams. Don't consider the weight of the beam here.

·         What's the maximum moment in the beam, in units of in-lb?

·         What's the max normal stress in the beam, in units of ksi?

·         Will the beam yield? Explain (with numbers)

·         What's the LIGHTEST W-beam that will not yield?

·         Use only the EngineeringToolbox.com website, as mentioned above. (hint: o=Mc/1 = M/S, where S=1/c. Work backwards to solve for S required. Of course we orient beams with the stronger side vertical.) e.
