Given that torques are the product of the forces and their moment arms with respect to the axis of rotation, quantifying both the torque and its moment arm enables interpretation of the effect of swimming technique on body alignment.
Higher value of moment arm can be derived by the existence of residual strength.
In backward pedaling within 45[degrees] of knee flexion, the patella has the greatest effect as a pulley, maximizing the moment arm of quadriceps femoris, biomechanically at this range the muscle is capable of generating the greatest torque which improves the muscular strength.
Because of the greater moment arm imparted to the deltoid with the Equinoxe[R] design, it was expected that less deltoid force would be required with this design.
Given an equivalent ground reaction force, the greater the joint flexion angle the longer the external moment arm, and therefore the greater the torque applied to bending the joint.
where: M--static moment; P--component of weight at a weighing point; r--static moment arm.
University of Arizona researcher David Raichlen and his colleagues have found that our modern human ancestors were better runner, because they have shorter limb bones, specifically Achilles tendon moment arm and calcaneal tuber from the calcaneus.
In a complete lesion however, cadaver studies of FCR have revealed a significant increase in its moment arm and subsequent increase in the load distributed through the radial carpus, thus enhancing the scaphoid displacement.
They even redesigned the bolting pattern for the fuel rails to the engine, using a crisscross pattern across the rail, rather than having brackets on a single side of a rail, thereby reducing the moment arm and stresses on the rail-remember, this is 2,150 psi of hydraulic pressure.
Because of the horizontal stabilizer's far greater moment arm, it doesn't have to create more than a small portion of the lift generated by the main wings.
The wrapping objects were created and placed accordingly to prevent bone penetration of muscle line as well as provide more realistic moment arm (MA) profiles.
