Need Help In Getting Started
In my statics class we are studying Rigid body equilibrium and when it got to 3D I get a little lost. Below are some homework questions I'm having a hard time starting. I get the free body diagrams but don't know where to go from there. I find that there are more unknowns than I have equations for.
I have provided links for the reactions that happen at certain types of connections. I also apologize for the bad scanning job on a couple of the images.
I appreciate any help. I need to finish this assignment asap.

Are you remembering to account for Torque?

I am accounting for moments (tourque). The 6 equations that I have to use are:
1) Force Equations:
-[tex]\Sigma F x =0[/tex]
-[tex]\Sigma F y =0[/tex]
-[tex]\Sigma F z =0[/tex]
2) Moment Equations
-[tex]\Sigma M x =0[/tex]
-[tex]\Sigma M y =0[/tex]
-[tex]\Sigma M z =0[/tex]
