Homework Help Overview

The discussion revolves around a mechanical aptitude test involving a system of gears and the effects of an applied force. Participants are exploring the behavior of a toothed axle when a force is applied to it, specifically questioning the direction of movement and the potential for the system to jam.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants are attempting to reason through the mechanics of the gear system, discussing the direction of rotation for each gear and how that affects the overall movement of the system. Questions about the reasoning behind potential outcomes, such as jamming, are being raised.

Discussion Status

There is an ongoing exploration of the mechanics involved, with some participants providing reasoning for their conclusions. A hint has been offered regarding the treatment of the gears as a collective system, and the discussion is delving into the implications of gear interactions.

Contextual Notes

Participants are encouraged to provide reasoning for their thoughts, and there is an emphasis on understanding the mechanics rather than simply stating outcomes. The original poster has provided an image link for reference, which may contain crucial information for the discussion.

hi everybody..

Homework Statement



we gave a force to this system (shwon in image) direction to the left;what will happen to this system (toothed axe) will move to the left or to the right or will be jammed?

welcome to pf!

hi zizodev! welcome to pf! :wink:

tell us what you think, and then we'll comment! :smile:​
 
i think will be jammed(frozzen)..:)
 
yes, but why?

you have to give a reason! :smile:

(hint: if we treat the two gears on the same axle as one, there are 5 gears in a circle :wink:)
 
yeah, because the (2 gear connected with axe) will turn Anticlockwise,the 3 rd gear will turn clockwise,the 4th anticlokwise,the last one will turn clockwise (and that the rank will slide to the left and the originel force given will make the rank slide to the left and that will make the system jammed! and what about the C choice is there possibility to occure.
 
that's right! :smile:

a more general reason:

since alternate gears go opposite ways, any circle of gears that is not fixed must have an even number of gears :wink:​
 
thank you tiny-tim for your help :)
