Torque of two locations with steel beams

Click For Summary
SUMMARY

The discussion centers on calculating the vertical support forces for two uniform steel beams, one of which is half the length and mass of the other. The larger beam has a mass of 1000 kg, while the smaller beam has a mass of 500 kg. The relevant equations used include torque (T = rf) and weight (F = mg). Participants suggest placing supports at each end of the larger beam to determine the support forces accurately.

PREREQUISITES
  • Understanding of basic physics concepts such as torque and force.
  • Familiarity with the equations T = rf and F = mg.
  • Knowledge of uniform beam properties and mass distribution.
  • Ability to analyze static equilibrium in mechanical systems.
NEXT STEPS
  • Study the principles of static equilibrium in mechanical systems.
  • Learn about torque calculations in various configurations.
  • Explore the concept of center of mass in composite objects.
  • Investigate support reactions in beam structures under load.
USEFUL FOR

Students studying physics, engineers working with structural mechanics, and anyone interested in understanding the dynamics of beam support systems.

Homework Statement



A uniform steel beam has a mass of 1000kg. On it is resting half of an IDENTICAL beam, on one side. The length of the beam is L. The block and its' smaller counterpart are being held up by two poles, one on each side of the larger beam. What is the vertical support force for each beam?

Homework Equations



T = rf

F = mg

[/B]

The Attempt at a Solution



[/B]
So, the fg for the smaller beam is 500(9.8)
The fg for the larger beam is 1000(9.8)

Where do I put the pivot points?
