Question

The above cantilever beam is steel (e= 30 x 106psi) with its cross section shown to the left (dimensions: 1.3'' wide x 2.2'' high). The upward-acting load, "q" , is triangular from x=3 ft to x=7.5 ft, and then rectangular from x=7.5 ft to x=15 ft. The triangular load magnitude at x=7.5 ft is the same as the rectangular load at x=7.5 ft. q is 8.7 lb/ft, fwall= 71 lb downward, and mwall= 387.6 ft-lb in the clockwise direction.

Answer 1

sorry I didn't know this
