What is the torque equation used in the context of a pulley system?
Torque = R + F
Torque = R * F * sin(Theta)
Torque = F / R
Torque = R - F

Why is the sin(Theta) term always equal to one in the torque equation for a belt and pulley system?
Because the belt is always perpendicular to the radius vector
Because the belt is always at a 30-degree angle to the radius vector
Because the belt is always parallel to the radius vector
Because the belt is always at a 45-degree angle to the radius vector

What is the effect of the upper and lower strands of the belt on the pulley?
The upper strand rotates the pulley clockwise, and the lower strand rotates it counterclockwise
Both strands rotate the pulley in the same direction
The upper strand rotates the pulley counterclockwise, and the lower strand rotates it clockwise
Both strands prevent the pulley from rotating
