Moment in 3d statics

  • #1
hi all, i'm new to this forum and have read through alot of the topics. i also tried searching the previous problems, but haven't found anything yet.

anyways, here's my question:

how do i find the reaction (normal) forces on points C, B, and A? i'm trying to do this with the vector method which i originally thought is supposed to be
rac X C + rab X B - rad X F.

the answer is supposed to be Nb=Na=.367F and Nc=.265 and which is what i got doing it the long and painful way of summing all forces and finding moments in 2d first.

thanks.

The attachment doesn't seem to work (or is it just me?).

You can do it vectorially, just make sure, you're doing it well. Maybe you can post your attempt.
