Anyone want to take a stab at this? I am helping a fellow friend, and I am too old I can't remember...

superposition like a motherfucker

[Edited on October 1, 2008 at 10:27 PM. Reason : nevermind, is it only rigid between A and C?]

[Edited on October 1, 2008 at 10:34 PM. Reason : or a rigid connection at B?]

Hard to tell. Maybe just a rigid beam, or just rigid at B?

I cant even solve part a of the problem

because it's statically indeterminate

so any ideas? I don't remember much of this stuff anymore. No, it's not from ncsu.

if the bar is rigid from A to D, that would help

because then you can solve for the compression and extension in B and C respectively with the force at D as a moment about A

from there, just use the sum of all forces in the vertical direction to get everything else you need

nevermind.
