Homework Equations
sum of forces = 0N
sum of torque = 0Nm
The Attempt at a Solution
Net force has to be already zero (T = mg). But, the torque isn't zero, otherwise this question would have another answer choice. But the gravitational torque should cancel with the tension torque right?
I looked at the answer and it says "the tension does not exert a torque." But, I've done so many of those pulley problems with pulleys w/ masses using forces and torque in which there are two tensions in the rope and the torque is (T1-T2) = I*alpha.
Why does the tension not apply in this problem as torque but does in the pulley problem?
