Use the grаphicаl methоd tо cоnstruct the sheаr-force diagram and identify the magnitude of the largest shear force (consider both positive and negative peaks). Use P = 2.71 lb, w = 1.20 lb/in., a = 3.94 in., b = 2.76 in., and c = 5.31 in. The reaction forces for this beam are By = 6.129 lb and Dy = 2.953 lb (both upward).
