SUMMARY

The discussion focuses on calculating the moments of a beam supported by motors, with specific thrust values and mass considerations. The user mentions a thrust of 580g generated by the motors and seeks to determine the mass center to understand the motors' effects on the beam. The moments provided are q=0.4905 Nm and q2=20 Nm, indicating the need for further calculations to find the resultant moment. The user expresses uncertainty about the available variables necessary for accurate calculations.

PREREQUISITES
  • Understanding of static equilibrium in mechanics
  • Familiarity with moment calculations and torque
  • Knowledge of mass center determination
  • Basic principles of thrust and its effects on structures
NEXT STEPS
  • Study the principles of static equilibrium in mechanical systems
  • Learn how to calculate moments and torques in beam systems
  • Research methods for determining the center of mass in composite systems
  • Explore the effects of thrust on structural integrity and stability
USEFUL FOR

Mechanical engineering students, structural analysts, and anyone involved in beam mechanics and static load analysis will benefit from this discussion.

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 ?
