Homework Statement
[/PLAIN]
https://web.njit.edu/~gary/111/assets/HW10_SOL.pdf
The problem is on page 3 of the document along with relevant solutions.
Homework Equations
F=ma, and Sigma Torques = (moment of inertia) * angular acceleration
The Attempt at a Solution
[/B]
I have been killing this problem for three hours now.
I was wondering why do they have in the solutions the net torque being (T2 - T1) * R.
Torque going in the counter clockwise direction should be positive and vice versa, so this seems wrong to me.
T2 is going in the clockwise direction of the pulley, so it should be negative, in my opinion.
Could anyone please weigh in why they have the order being T2 - T1, and not T1 - T2 [which is what I did]?
Thanks!
