Load Distribution

Moments.

Measure the distance of load is from each support. Develop a formula from the information. Calculate then you have the answer.

If you need more information most mechanical, structural engineering books will show you how to figure load supports and gives some examples. It's up to you to develop the vector formula.

More information from Google for you.

There is some good info in this link.

Good luck with your studies.

This is elementary "Statics". This is usually learned in the first semester of the Freshman year in engineering college. Go find a "Statics and Strength of Materials" college textbook and study it. That's about the only way to learn how to do this calculation....

It is NOT as trivial as it appears by the made comments. The 1st question is : is your system statically determined or is is hyper - static? In the 1st case the basic static equations are the tool to use. It is more complicated in the second case for which you have to make assumptions about the different stiffness of the supporting points and about the deformation under load of the structure itself. To give you an example if you have a beam on two supports then it is easy to determine load at each end. But if you have it on 3 supports the load on the middle point will depend on the support stiffness and on the beam deflection. But this load will reduce the two other how much every one is not clear if a good analysis is done.
