This decision was made in the interests of maneuverability, since the center of thrust is in the outer part of the disk thus giving a larger turning moment arm.

The lengths of the ilium and ischium and their angles relative to the acetabulum are functionally important as they determine the moment arms for the hip extensor muscles that provide momentum during locomotion.
33.
For example, using a long wrench, which has a large moment arm, to open a nut requires less force than using a short wrench, which has a small moment arm.

35.
In particular, if the forward tip of the ski rotated to the side, the force was transmitted through the length of the ski to the boot, forming a huge moment arm.
36.
A tighter grouping may be achieved with such a stabilizer, which adds mass extending outward on a moment arm, usually mounted perpendicular to the bow riser, aligned with the arrow path.
37.
If the aircraft is to be naturally stable, the foreplane s size, lift slope and moment arm must be chosen so that it does not overpower the stabilizing moment provided by the wing and tailplane.
38.
If the force is perpendicular to the displacement vector "'r "', the moment arm will be equal to the distance to the centre, and torque will be a maximum for the given force.
39.
Any fin must attach directly on to the rear part of the wing, giving a small moment arm from the aerodynamic center, which in turn means that the fin is inefficient and to be effective the fin area must be large.
40.
Calculating this requires knowing the vehicle's sprung weight ( total weight less the unsprung weight ), the front and rear roll center heights and the sprung center of gravity height ( used to calculate the roll moment arm length ).
