So in the diagram, where did DF go? Or it doesn't move?
Yes using the diagram the moment at B should equal 15...my statics was wrong but i know wat went wrong now :-)
Yes, i think so. I know that the displacement diagrams can bend at pins but must pass through the roller/rocker supports etc, and remains zero at fixed supports. And initially it goes in whichever direction the force is acting.
Thanks a lot for going through this stuff with me! i know that...
We havnt learned kennedy's theorem yet and googling it turned up nothing educational either...or at least nothing i could understand. Is there a simpler way about it?
Dear Radou
Yes that is the general principal of virtual work as i understand it too but its very confusing to apply.
Ive realized, since posting the diagrams up, that i made a few mistakes in my attempted solution. Since it takes so long for attachments to be approved maybe i can just...
Homework Statement
Im having real trouble with drawing diagrams for virtual work. Can someone please, please help me!
We were asked, in the diagram i posted, to find 1)vertical reaction at F, 2) all reactions at A, 3) bending moment and shear force at B using virtual work.
i think i...
