Problem 2 (a) Use the Müller-Breslau Principle to draw the influence lines for the reactions and internal forces noted below each beam. Consider a moving unit load of 1 kip and calculate critical values. (i) 8' 4'- A D B C E hinge 16' 8' MA, RAY, RBY, VB (left of support B), VB (right of support B), VE, ME 10'- (ii) A -10'- B -10'- 5+ RAY, RBY, VC, Mc (b) Consider the beam shown in Problem 3-a-ii. Suppose it is loaded with a uniformly distributed live load of 200 lb/ft, a uniformly distributed dead load of 500 lb/ft, and a concentrated live load of 10 kips. Determine the maximum positive moment and shear at C.
