Homework Statement
A stick of mass M is held up by supports at each end, with each support providing a force of Mg/2.
Now put another support somewhere in the middle, say at "a" distance from one support and "b" distance from another.
What forces do the three supports now provide? Is it solvable?

The Attempt at a Solution
Here is an image of my scanned work. (The top problem I am fairly certain I have correct, It wanted me to find the ratio of Jupiters escape velocity compared to Earths. So just ignore that one. Look at problem number 2!)

Basically I tried to find the mass of each section of the stick using linear density. Is this the wrong way to go about it? I feel like it is considering my professor is asking "is it solvable?"
Thanks!
