Halc,Is the wheel going to jump up due to the angular acceleration/deceleration, assuming angular acceleration is bigger than gravitational acceleration?You know it will not.
The fact that you got the α and ω vectors correct suggests you're not completely uneducated, and yet you ask a question like that. Now why is that?
For the third time, you are adding vectors of different units (bold above), meaning you're ignoring everything I say and intend to continue to do so. Hence I see no reason to continue this troll discussion.
I assure you, this is not trolling.
Please, have a look:
The figure shows the setup from my question.
If we take a realistic time, let's say dt = 0.1s for the braking.
When Torque - T, Omega - w, Inertia - I, Angular acceleration - a
T = I (dw/dt) + (dI/dt) w
We know that dI/dt = 0 during the breaking, so the torque
T = I (dw/dt)
T = I a
Please, tell me a good reason why the wheel is not going to jump up if the angular acceleration a is bigger than gravitational g?
