In order to link these into a logical sequence, how do they fit together
I = rotational inertia a = angular acceleration (I know a different symbol is usually used)
τ= force x moment arm distance
The Attempt at a Solution
so....to get my head around how these interact
Torque is the amount of rotational force applied to a body.
rotational inertia is how much the body will resist this force
angular acceleration is how dpenedne ton these two.
If I applied 5Nm of torque to a body that had a rotational inertia greater than this then the body wouldn't move and its angular acceleration would be 0
If I applied 5Nm of torque to a body that had a rotational inertia less than this then the body would move BUTwhat if it moves at a constant velocity and doesn't accelerate ? It still has 0 acceleration but is moving ?
I unsure how torque can length of moment arm x force AND moment of inertia x angular acceleration
if there is is 0 angular acceleration then moment of inertia x 0 = 0 so ther eis 0 Torque
but if I'm applying 5Nm of toruqe how can there be 0 torque ?
I must have missed something fundamental somewhere
