Its about this flywheel and what happens if you use a thicker cord that has to overlap itself but is the same length as the thinner one. Same force applied as before. Neglecting the mass of the thicker cord.

A constant force of 3N is applied to the cord as before.
Will the time taken for the thicker cored to unrap be longer, shorter or the same as the thin cord? Explain your answer.
Neglect the mass of the thicker cord."
By the way, have you decided on what uni you're going to? I'm off to St Andrews to study Physics.

Anyway... you haven't typed the whole question!
But, er... Assuming Torque is the same, moment of inertia is greater I think.
a = T/I
Time taken would be longer than the thin cord.
Of course I could be wrong.
