(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The bar ABCDE is subjected to three forces: F1 = 75 N and lies along DC, F2 = 50 N and lies along ED, F3 = 40 N and lies along CB. In addition,AB moves 3sqrt2 m on xy plane, BC moves 2 m along y plane, CD moves 1 m along z plane, and DE moves 1 m along x plane. Determine the moment these three forces create about the segment AB. The diagram for this problem is attached to this post. Thanks!

2. Relevant equations

Cross Product of Vectors

Dot Product of Vectors

Scalar Triple Product of Vectors

3. The attempt at a solution

I'm fairly sure that the problem uses a formula similar to the one used to find the moment about a point, except I'm unsure of how to approach the problem when the moment is supposed to be found about a segment.
