Draw the envelopes for maximum shear and moment in a 24-ft-long simply supported beam produced by a live load that consists of both a uniformly distributed load of 0.4 kip/ft of variable length and a concentrated load of 10 kips (Figure P12.42). The 10-kip load can act at any point. Compute values of the envelope at the supports, quarter points, and midspan.
