The rigid beam shown here is supported by a pin at D and an A992 steel guy wire AB of length 6 ft. The diameter of the wire is 0.2 in. The beam supports a uniformly distributed load of 200 lb/ft. The beam and the wire remain elastic. LBD = 10 ft, LCD = 2 ft. 1(a) (5%) Neatly sketch the free body diagram and clearly label the external forces and the reactions on the member. 1(b) (10%) Using the symbols prescribed in the figure, resolve the equilibrium equations and determine the reactions at the ends A and D. 1(c) (10%) Section the beam at any arbitrary point, x and express the internal shear, V and moment, M at the point as a function of x. 1(d) (5%) Using the shear and moment equations of 1(c), calculate the internal loadings at C. 1(e) (10%) Draw the shear and moment diagrams.
