Published	10/26/2023	If the Biceps is eccentrically contracting, what is the effort force and resistance force? How does this affect the lever?
Published	10/26/2023	When a lever is in rotational equilibrium, the muscle acting on the lever is contracting {{c1::isometrically}}. In such a case, labeling the muscle as…
Published	10/26/2023	When a muscle is contracting eccentrically (actively lengthening), the muscle must be acting in a direction opposite to the motion of the segment; tha…
Published	10/26/2023	Mechanical Advantage Equation
Published	10/26/2023	The {{c1::second}} class lever is always efficient, M Adv greater than one, although the magnitude of the ratio of EA to RA will vary.   In …
Published	10/26/2023	Third Class Levers, {{c1::EA}} is always smaller than {{c1::RA}} since the effort force lies closer to the axis than the resistance.M Ad of the third …
