Composite bats, tested after they were already broke in, showed performance standards well beyond the accepted ball exit speed ratio ( BESR ) Test.
32.
Due to the Glauert model, efficiency is below the Betz limit, and asymptotically approaches this limit when the tip speed ratio goes to infinity.
33.
Since tip-speed ratio is given by the aforementioned expression, variable speed wind turbines can operate at maximum efficiency over all wind speeds ( ideally ).
34.
Our defense needs to step up and, offensively, we'll have our hands full with the size-speed ratio that West Virginia will have in Morgantown ."
35.
Defensive coordinator Dick LeBeau commented about Allen : " We always liked his size to speed ratio and he's got an innate feel for the ball ."
36.
Differential roller screws modify the rotational speed ratios between the rollers and the screw by varying the flank angles and contact points of the threads or grooves.
37.
Renfro for his time had an excellent size / speed ratio, being 6 3 feet, around 210 pounds and could run the 100 yard in 9.6 seconds.
38.
The output shaft of the gearbox is permanently connected to the final drive, then the wheels, and so both always rotate together, at a fixed speed ratio.
39.
The two-gear wheels offer two speed ratios-1 : 1 ( no help, no extra torque ) and 2 : 1, providing 100 % more hill climbing force.
40.
Solving the optimal speed ratio is complicated by the dependency on \ gamma and the fact that the optimal speed ratio is a solution to a cubic polynomial.
