Hello, Skycart. The PF rules state we are not allowed to tell you how to approach or solve your homework problem. You must list relevant equations yourself, and show your work; and then someone might check your math.

skycart as nvn said list the equations and you will get yourself started. Also could you please explain M,F, and V

V, F, and M would be internal shear force, axial force, and moment.

Ahh yes how could I forget V as shear force. Ok thanks.

Thanks for the info about posting on the forum. I didn't list equations because there are not really any conventional equations like in physics. About the only thing to do is sum the x and y forces and then sum the moments. V stands for shear force. M stands for moment. F stands for axial force. Thanks for the replies!

These are equations no?

Now how would you go about getting reasonable equations for that section?
