How to find the moments?

The Attempt at a Solution

I looked of a few books in last several hours, but without any success. In every similar problem the moments are given. Only thing I know for sure is that I don't have the all variables to calculate it ...


Thanks for understanding

Let's see an attempt which is a must before we can help. Also, how is the beam supported?

Its supported by thrust by motors at the both sides at the bar...

I am thinking about a solution but something is missing ... its doesn't feel right...
The motors are creating thrust 580g, so i have to find the mass center so i can see how the motors effect the bar?

Am i right ?
