## Homework Statement

I have a shear force diagram and im asked to find the magnitudes of the point loads and where are they situated

My question is, what am I looking for to find the point loads in a shear force diagram?

## Homework Equations

## The Attempt at a Solution

I assume you are looking at point loading along the length of a beam. How does the shear force change from one side of the point load to the other? Do you have any examples of shear force diagrams in your textbook involving point loads?

here is an example

10 m light horizontal beam

it has points ABCD

A at 0m, B at 2m, c at 8m and D at 10m

it goes positive 38N at A then to 34N at B then straight down to negative 16N the line then goes to C to negative 28N and then straight up to positive 30N and then to D and straight down to 0.

Im just not too sure what exactly to look for to determine where a point is.

A. It varies continuously

or

B. It undergoes a jump change discontinuity

I would go with B on your question.

I would go with B on your question.

Right. Now how are these jump changes in shear force related to the point loads? Hint: see my first reply.
