    Beam Moment
AI Thread Summary
The discussion revolves around calculating moments for a beam supported by motors, with specific values provided for thrust and moments. The user is struggling to find the necessary variables to solve the problem, noting that similar examples typically provide moments. There is a focus on determining the center of mass to understand how the motors' thrust affects the beam. The user expresses uncertainty about their approach and seeks clarification on the support mechanics. Understanding the mass center is deemed crucial for solving the problem effectively.

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 ?
