Solving Cantilever Problem with Axial Load & Bending Moment

[Tino]

Hello,

Well, I am working on this home problem I have, but I am struggling.
The lecture has told us that the problem involves both Axial load and Bending moment.
But I don't know what equations I need to use to calculate this.
I am trying to find out the maximum stress on this cantilever problem.
Below is half of the model, but it is symmetric, so the other half would be the same.
This plate is restrainted by Pin A, and on the other symmetric plate Pin B (in the same location as Pin A) the pin passes through but the plate is allow to move horizontally.
A Load 400N is applied at Pin A horizontally.
The O is an actual hole, there's four holes altogether in the plate.

The dimensions of the whole plate I have got, just want to understand what equations to use.
The # are just empty space, pin A and the holes are aligned in the center.

Hi there,

Thank you for reaching out with your question. It sounds like you are working on a cantilever problem that involves both axial load and bending moment. In order to calculate the maximum stress on the cantilever, you will need to use equations that take into account both of these factors.

For the axial load, you can use the equation σ = P/A, where σ is the stress, P is the applied load, and A is the cross-sectional area of the cantilever. This will give you the stress caused by the axial load alone.

To calculate the bending moment, you will need to use the equation M = F*d, where M is the bending moment, F is the applied force, and d is the distance from the applied force to the point where you are calculating the stress. This will give you the bending moment caused by the applied load.

Once you have calculated both the axial stress and bending stress, you can use the principle of superposition to add them together and get the total stress on the cantilever. Keep in mind that the maximum stress will occur at the point where the axial stress and bending stress are both at their highest values.

I hope this helps you with your problem. If you need any further assistance, please don't hesitate to ask. Good luck with your project!
