Why is the direction in which the D.C. motor turns reversed here?

    Direction Motor
AI Thread Summary
The discussion centers on a discrepancy between the direction of rotation of a D.C. motor in a worksheet and a textbook. The worksheet indicates that the motor turns clockwise, while the textbook states it turns anti-clockwise. Participants question the interpretation of the figures, particularly Figure 6.2, which shows movement but lacks clarity on the direction of rotation. There is confusion regarding the upward and downward movements of components A and D and how they relate to the overall rotation direction. Clarification on these points is needed to resolve the conflicting information.

I tried Fleming left hand rule and no matter what doesn't AB move downwards?

Where does it say it turns clockwise?

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.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
