Simple beam
Simple beam
(OP)
Hello,
Could you help me with one problem.
I've simple beam (see attachment please).

I've assumed that displacement v1 = 1 (therefore end of the beam is anchored - also in attachement).
In handbook I found that Force matrix for that case is equal to:
0
12EI/L^3
6EI/L^2
0
-12EI/L^3
6EI/L^2
And I have question for above matrix. Could you tell me why M2 = M1 ?
Thank you very much,
Lukasz

RE: Simple beam
i don't understand your original "force matrix", can you clarify the terms ?

if you apply only a moment at the free end, then of course M2 = M1.
