W = Torque * distance

3. The Attempt at a Solution


The net torque is 8*.09-11*.06 = .06, and the distance moved is 4pi, because 2 full rotations, but this is not one of the choices...

Edit: never mind, delete the thread. (I cannot find delete button)

Edit 2: Replaced with new problem, that I do need help with.

The question states that the amount of string unraveled is 1 m, not 2 m. (Oops, I did not see your second post.)

Note that the torques act in the same direction.

FAQ: Solving for Net Torque: W = Torque * Distance

1. What is net torque and how is it different from regular torque?

Net torque refers to the total torque acting on an object, taking into account all the forces and distances involved. It is different from regular torque, which only considers a single force acting on an object.

2. Why is it important to solve for net torque?

Solving for net torque allows us to understand the rotational motion of an object and predict its behavior. It is crucial in analyzing and designing mechanisms and machines.

3. How do you calculate net torque?

Net torque can be calculated by adding up all the individual torques acting on an object, taking into account their magnitudes and directions. The formula is W = Torque * Distance.

4. What is the relationship between force, distance, and torque?

Force and distance are the two factors that determine the magnitude of torque. The farther the force is applied from the axis of rotation, the greater the torque. Additionally, the direction of the force also affects the direction of the torque.

5. Can net torque be zero?

Yes, net torque can be zero if the total torque acting on an object is balanced. This means that the clockwise and counterclockwise torques cancel each other out, resulting in no rotational motion.
