Use the grаphicаl methоd tо cоnstruct the sheаr-force and bending moment diagrams and identify the magnitude of the largest bending moment (consider both positive and negative peaks). Use w = 240 lb/in., a = 0.875 in. and b = 1.500 in. The reaction forces for this beam are Ay = Dy = 180 lb (both upward).
