These relations are important because they define the maximum performance of a device in terms of velocity ratios determined by its physical dimensions.
12.
The angular-velocity ratio may not be constant or equal to that of the pulley diameters, due to slip and stretch.
13.
Reeving to disadvantage adds an extra sheave to change the direction of the pulling line, which increases friction losses without improving the velocity ratio.
14.
The curves in Figure also show the optimum values of the velocity ratio and the range of off-design for various types of stages.
15.
The selected angles of the recesses and the incline on the locking piece produce a velocity ratio of about 4 : 1 between the bolt carrier and the bolt head.
16.
There are indications that the brain uses various cues, in particular temporal changes in disparity as well as monocular velocity ratios, for producing a sensation of motion in depth.

BRDRC made a number of important contributions to the field of rotordynamics such as a better understanding of fluid-induced instabilities, advanced models for understanding shaft crack behavior, insight into rubbing malfunctions between stationary and rotating parts, and enhancement of the rotordynamic equations with a new variable lambda ( ? ) which denoted " the fluid circumferential average velocity ratio ".

BRDRC made a number of important contributions to the field of rotordynamics such as a better understanding of fluid-induced instabilities, advanced models for understanding shaft crack behavior, insight into rubbing malfunctions between stationary and rotating parts, and enhancement of the rotordynamic equations via introduction of a new variable lambda ( ? ) which denoted the fluid circumferential average velocity ratio and more accurately modeled hydrodynamic effects.
