Biomechanics Chapter 3 exam (chapter 13) The perpendicular distance between the line of force and the axis defines what? Torque is the angular analogue of what? Which of the following is a characteristic of torque? In the human body, most of the lever systems formed by muscles pulling on bones are what class?
The moment arm or lever arm is the perpendicular distance between the line of action of the force and the center of moments. Moment = Force x Distance or M = (F)(d) The Center of Moments may be the actual point about which the force causes rotation. It may also be a reference point or axis about which the force may be considered as causing rotation.

Let's start with the line Ax + By + C = 0 and label it DE. It has slope#N#− A B#N#\displaystyle-\frac {A} { {B}} −BA#N##N#.
Find the perpendicular distance from the point (5, 6) to the line −2x + 3y + 4 = 0, using the formula we just found.
