Solving Tension in Simple Pendulum at Centre Point

Click For Summary

Homework Help Overview

The discussion revolves around a simple pendulum and the calculation of tension in the string when the pendulum is at its center point. Participants are exploring the relationship between tension, weight, and centripetal acceleration in this context.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Some participants attempt to equate tension with weight, while others challenge this view by emphasizing the need for tension to account for centripetal acceleration. Questions arise regarding the forces acting on the pendulum at the center point.

Discussion Status

The discussion is active, with differing opinions on the correct interpretation of the forces involved. Some participants provide affirmations while others offer corrections, indicating a mix of agreement and disagreement without a clear consensus.

Contextual Notes

Participants are navigating assumptions about the forces acting on the pendulum, particularly in relation to gravitational force and centripetal acceleration. There is also a mention of potential misunderstandings regarding terminology and identities within the discussion.

Of course it is. :) You are damn right!
 
No, you are NOT correct.
At all times, the tension must provide the CENTRIPETAL ACCELERATION of the attached mass as well.

oh yes. as well as the acceleration due to gravity. isn't it? now the force must be greater than mg.
 
Quite so! :smile:

Thanks a lot!
 
I'm not an aldrino. Please, I hate aldrinos. :frown:

Oh! I am sorry. just a spelling mistake. Who are aldrinos, by the way?
