Shear Force Diagram of a Simply Supported Beam


In a previous question found here: Reaction forces on a simply supported beam We calculated the reaction forces at each of the supports of the simply supported beam in the diagram below:

Simply Supported Beam
Simply Supported Beam


From the other question, we know that the reaction force at the left support in the y direction is 3.25kN upwards and in the x direction, the reaction force is 0N. We also previously calculated the reaction force at the right support in the y direction to be 0.75kN upwards.

The beam is 4 metres long with the 5kN force 1m from the left side and the 1kN force in the center of the beam.

Using this information calculate and draw the shear force diagram (SFD) of the beam

Previous Question
Shear Force Diagram of a Cantilver Beam
In this question we will use the cantilever from question 11. we have already worked out the reaction forces and drawn the free body diagram, this makes drawing the shear force diagram easier because we start with all the data that we need.
Next Question
Bending Moment Diagram of a Cantilever Beam
In this question we will use the cantilever from question 11. We will now draw the Bending Moment Diagram for this cantilever beam. Because we have already determined the Shear Force Diagram, this is quite a simple procedure.
