Explanation:
The relationship between the magnitude of the force of tension and the force of friction is; Ff = (r/R)Ft
<h3>What is Rotational Acceleration?</h3>
We are given;
mass of spool = M
Radius = R
moment of inertia = I.
Now, the spool is not moving and as such;
r < R which means there is net torque = 0
Thus;
Ff × R = Ft × r
>> Ff = (r/R)Ft
Finally, the angular acceleration is expressed as;
α = a/R
