Point Loads Calculation with more than 2 supporting points
Hi,
I am dealing with large equipment ( few thousand KG in weight), I would like to apply the vibration isolators (spring) in order to reduce the vibration of the equipment to the building. I have to calculate the point loads of the equipment (i.e. the weight at every position where vibration isolator will be installed), in order to size the vibration isolators.
I am able to calculate the point loads with 2 supporting points, as shown in the below image, with the assumption that the beam/line does not deform when the force/weight (W) is applied.

But, I do not know how to calculate for 3 supporting points (as below shown), as well as even more supporting points.

Can anyone teach me how to calculate it, or give me the link of a website that explain it? I did try to search the web using Yahoo and Google with the keywords "point load", "point load calculation", "load distribution" and "weight distribution", but the closest that I could find was the point loads with 2 supporting points.
Thanks.
