Atwood Machine: Reduce Exp Errors By Stabilizing Masses

Click For Summary
SUMMARY

The discussion focuses on the Atwood Machine and how tying a string equal in length to the string connecting the pulley can reduce experimental errors. This setup ensures that both masses travel the same distance when one is dropped, thereby minimizing discrepancies in measurements. The conversation highlights the importance of understanding the assumptions of an ideal Atwood Machine and the factors that prevent its perfect construction. Participants emphasize the need to clarify what constitutes experimental errors in this context.

PREREQUISITES
  • Understanding of Atwood Machine mechanics
  • Familiarity with experimental error concepts
  • Knowledge of basic physics principles related to motion
  • Ability to interpret scientific literature, such as Wikipedia articles
NEXT STEPS
  • Research the assumptions of an ideal Atwood Machine
  • Explore methods to mitigate imperfections in experimental setups
  • Learn about the types of experimental errors in physics
  • Investigate the role of string tension in mechanical systems
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in experimental design and error reduction in physical experiments.

Homework Statement



String that is equal in length to the string connecting the pulley is sometimes tied to the bottoms of the two masses, where it hangs suspended between them. Explain why this would reduce experimental errors.

Homework Equations





The Attempt at a Solution



I'm not sure but does the string help stabalize the masses when one is dropped so they travel the exact same distance?

The question asks why it helps to reduce experimental errors. It's not referring to mechanically stabilizing anything.

What are the assumptions for an ideal Atwood Machine? What keeps you from being able to build an ideal/perfect AM? What could you do to mitigate these imperfections?

But I don't understand what the experimental errors are... how could string have affected it in any way?

Did you read the link that I posted? The clues are in there. (Or in your textbook's description of the AM)
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
