1. ### Plotting stress tensor in MATLAB, Parametric Surface

First off, I'm not sure if matlab questions go here or not, or if they are even dealt with on this forum. If not more or remove I guess. I am no matlab wiz so this is mind-boggling to me. I am given a state of stress at a critical point of a component and told to plot a 3D parametric surface...
2. ### Boundary conditions for a 4th order beam deflection equation

thanks, I was getting confused because some sites had "common beam" equations that were different than others.. until i realized that the supports were on different sides and thus their coordinate system was changing. now it makes sense.
3. ### Boundary conditions for a 4th order beam deflection equation

What would the boundary conditions be for a fourth order differential equation describing the deflection (elastic curve) of a propped cantilever beam with a uniform distributed load applied? i.e. a beam with a built in support on the left and a simple support on the right. I need 4 obviously but...
4. ### A column under thermal stress

I have a problem with a constrained column under thermal stress where I am to find the reaction forces at the supporting ends of the column due to its own weight after being heated. Attached is the problem, equations used, and my solution attempt. I tried to solve for the reaction forces...

The more I work on this the more confused I get. For now I just want to be able to clearly understand the simple one material model, and have an answer in front of me that I don't have to second guess. ugh.
