Homework Help Overview

The discussion revolves around the direction of rotation of a D.C. motor as presented in different sources, specifically a worksheet and a textbook. Participants are examining the apparent discrepancy between the clockwise and anti-clockwise designations of the motor's rotation.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to understand the difference in rotation direction as indicated in their worksheet compared to their textbook. Some participants question the clarity of the figures referenced and whether the movements described imply a specific rotational direction.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the figures and the descriptions provided. There is an exploration of different interpretations regarding the movement of components A and D, but no consensus has been reached yet.

Contextual Notes

Participants are referencing specific figures from their materials, which may not be fully described in the thread. There is an indication of potential ambiguity in the visual representation of the motor's operation.

in fig 6.2, A moves upwards while D moves downwards so doesn't it mean clockwise?
 
I don't see anything in the figure which suggests A is moving upward and D is moving downward.
