For the following beam:
a) Draw the Shear diagram (20 points)
b) From the shear diagram, determine the maximum shear (positive and negative) and the absolute value (5 points)
c) Draw the Moment diagram (20 points)
d) From the moment diagram, determine the maximum moment (positive and negative) and the absolute value (5 points)
Note: There is a hinge at B, the beam is continuous at C, there is a roller support at A, and a fixed support at D. The concentrated counter-clockwise moment is applied to the right side of B. You do not need to provide the formula for shear and moment, but you need to specify the value of shear and moment and the sign of the slope of shear and moment diagrams (positive, negative, or zero at each node). You also need to specify the concavity of the curves (for each part specify: concave upward, concave downward, or straight line).
