Which of the following statements related to shear diagrams is not correct?

Before a shear diagram is drawn, all load distributions should be simplified into point loads
Shear diagrams begin and end at zero shear
The shear force at a point is the total external load on the beam at that point
The shear line representing a uniformly distributed load is linear

Explanation

Answer: C - The statement “the shear force at a point is the total external load on the beam at that point” is not correct. Correctly stated, the shear force at a specific point on a shear diagram can be found by summing the external loads and reactions that are occurring perpendicular to the beam to the left of the specific point.
