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...
5. ### Beam (composed of two materials) Axial Loading

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.
6. ### Beam (composed of two materials) Axial Loading

*Edit: "To answer your third question, if you apply only an end force to the rod, but you apply no other applied load (not even gravity), then the force in the rod is constant along the length of the rod. Yes, the limits of integration should be 0 to x." You say the force in the rod is constant...
7. ### Beam (composed of two materials) Axial Loading

Here is a simplified version of this problem. In this version we just have one material. Can I do what I have done in that image? Since total deformation of the beam is 0 can we think of it as the beam first being compressed by its own weight, and then be extended by the upward...
8. ### Beam (composed of two materials) Axial Loading

Some thoughts that I need clarifying. 1. In the sketch in my last post are P1 and P2 constant through out the beam? Like I said it's been a while since I have studied this material, but I want to say yes. 2. If they are constant, do P1 and P2 share the load W(weight of the beam) equally...
9. ### Beam (composed of two materials) Axial Loading

Hi Im trying to help a friend of mine out with this problem he has in a solid mechanics class he is taking, but it has been awhile since I took that course so i was hoping you guys could help me help him :) Here is the problem he gave me. in that image p1 p2 and E1 E2 are the...
