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?

in my worksheet, AB turns in clockwise direction , while in my textbook, it turns in the anti clockwise direction.
so may I know why is this the case?

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 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
