Which of the following best describes torque?
a. The force a muscle generates
b. A force times the perpendicular distance from the line of force to the axis of rotation
c. A force times the distance measured along the lever from the line of force to the axis of rotation
d. The distance a muscle can move
ANS: B
Torque equals force times distance. The distance must be represented by the moment arm of the
force, not just the direct distance as measured up the lever. The moment arm is the perpendicular
distance of the line of the force from the axis of rotation.
