Question 1

Properties of Shear and Moment Diagrams

Answer 1

• The area of the shear diagram to the left or to the right of the
  section is equal to the moment at that section.
  *The slope of the moment diagram at a given point is the
  shear at that point.
  *The slope of the shear diagram at a given point equals the
  load at that point

Question 2

The following are some important properties of shear and
moment diagrams:

Answer 2

*The maximum moment occurs at the point of zero shears.
*When the shear diagram is increasing, the moment diagram
is concave upward.
*When the shear diagram is decreasing, the moment diagram
is concave downward.
