Kinematics of Rotational Motion (Gears)

Click For Summary

Homework Help Overview

The discussion revolves around the kinematics of rotational motion, specifically in the context of gears and their relationship to displacement and velocity. The original poster is exploring the assumptions related to initial conditions for different gears in a system.

Discussion Character

  • Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • The original poster questions whether the initial conditions for Gear A can be assumed to apply to Gear B/Drum C. Some participants suggest that rotational and translational kinematics can be applied, while others seek clarification on the meaning of the terms used.

Discussion Status

The discussion is ongoing, with some participants providing clarification on the application of kinematic principles. There is an exchange of questions and confirmations regarding the assumptions made about the gears.

Contextual Notes

There appears to be some confusion regarding the distinction between displacement and velocity in the context of the problem, which may influence the interpretation of the question.

Homework Statement


Since
Gear A
--------
Vi=0
t=12s
θ=40∏

as given in the question, can I assume that Vi=0 t=12s for Gear B/Drum C as well?
If not why?


Thanks..

You can apply rotational and translational kinematic.
For question (d) the question is displacement, answer given velocity
 
what do you mean?
