moment arm

moment arm

the distance between an applied force and the fulcrum (pivot or axis) in a lever system.

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.
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.
2005), the force produced by elbow flexors in quasi-static exercises increases with the load moment arm, which highly affects the direction and magnitude of joint internal forces.
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.
Sigmund emulates manufacturing process variations following the ASME standard, as Well as assembly process sag, shift, moment arm and gravity effects.
Additionally, because of mass location and a longer hosel than is typical of the Company's patented S2H2(R) Technology, Callaway Golf designers were able to position the CG more toward the heel for a shorter moment arm to provide easier workability.
Caption: Figure 1 Medializing the CoR with a glenosphere prosthesis design in which the thickness is less than its spherical radius (left image) to further increase the deltoid abductor moment arm lengths relative to the Grammont glenosphere design having a thickness equal to its spherical radius to place the CoR on the face of the glenoid (right image).
The design goal was to maximize the locking torque of the SCKM at/near full knee extension by optimizing the moment arm as a function of knee angle while minimizing the torque that is required to drive the knee during the swing phase of gait when the mechanism is unlocked.
To produce the same magnitude of moments during the tests with a moment arm of 533 mm (21 in), test loads were calculated and were applied to the rail (as given in column 4 of Table 2).
