I'm trying to find some basic physics information. Suppose you have a (massless) beam, supported at two points, 10 feet apart. You have a force (m*g) of 100 newtons resting on that beam, say 4 meters from the left point (6 meters from the right)... How much force does that exert on each point, and how do you calculate it...? It seems this would be a simple physics example but I can't seem to find any info on an example like this. I'm working on a trailer hitch problem and the info would be useful... Thanks.
