Problem 1

For the beam shown, determine the support reactions at A and B as well as the internal tractions (normal force, shear force and bending moment) at points D and E. Point D is 5 ft left of the roller at B and point E is 5 ft right of B. The beam has a self-weight of 68 lb/ft along it's length.

Answers: F_A = 1000 lb; F_B = 2040 lb

N_D = 0; V_D = -770 lb; M_D = 1725 lbft

N_E = 0; V_E = 340 lb; M_E = -1050 lbft
