Factors In Use of Anatomical Levers

** A lever scheme can become unbalance when enough torque is made.

** Torque = Force (from the muscle) x Force Arm (distance from muscle insertion from the joint)

** Torque is the rotating effect of a force; interior the body it caused rotation round a junction.

Examples

1. How much torque needs to be produced to move 47 kg when the RA is 0.25 m and the FA is 0.1 meters?

•We can Use the formula F x FA = R x RA

•Note: A Newton is the unit of force required to accelerate a mass of one kilogram one meter per second per second.

** FA the expanse from junction (i.e. axis or folcrum) to insertion of the force.

opposition could be a weight, gravity, etc.

RA the expanse from joint to the center of the resistance.
