The beam is subjected to a uniform live load of 1.2 kN/m, a dead load of 0.5 kN/m, and a single live load of 40 k and (c) the maximum positive shear at E. Assume A and C are rollers, D is a pin, and B is an internal hinge (20 points) Determine (a) the maximum positive reaction at D, (b) the maximum positive moment created by these loads at E A 4 m PROBLEM 2 Use the portal method and determine (approximately) the reactions at C. (20 points) 4 m PROBLEM 3 Determine the slope and deflection at point C of the beam shown. El is constant. Use any method discussed in class.
