Shear and moment diagram--Need help!

Homework Statement

On the attached question:

Fpy = 10 N
Ffy = 10 N

Mp = 0.15 Nm
Mf = 0.45 Nm

Homework Equations

Draw the shear and moment diagrams.

The Attempt at a Solution

If you look at the answer I posted, I believe the shear diagram (top) is correct. I'm not sure about the shape of the moment diagram though. Perhaps it would slope to zero on both ends. Any suggestions? Thanks!

We would not know, because you did not show the supports on your first diagram.

Hello Jim,

Thank you for reaching out for help with your shear and moment diagrams. Based on the information provided, it seems like you are on the right track with your shear diagram. However, for the moment diagram, it is important to remember that the slope of the moment diagram will be equal to the shear force at that point. Therefore, the slope would not necessarily be zero on both ends, but rather would be equal to the shear force at that point.

In order to accurately plot the moment diagram, you will need to take into account the change in shear force at each point along the beam. This will allow you to determine the slope of the moment diagram at each point and plot it accordingly. I would recommend going back and reviewing the equations and concepts for shear and moment diagrams to ensure that you have a clear understanding of how to plot them accurately.

Additionally, it may be helpful to consult with a classmate or your professor for further clarification and assistance. They may be able to provide additional tips and resources to help you with your diagrams.

I hope this helps and good luck with your assignment! Remember to always double check your work and ask for help when needed. Science is all about collaboration and problem solving, so don't be afraid to reach out for assistance.
