11. Maximum efficiency occurs at one tip-speed ratio only. 12. Using these numbers we can compute the following speed ratios between the front and rear sprockets 13. The next area of focus for Belichick is in high-production players who fit a size-speed ratio . 14. Prentice more than fits the Belichick size-speed ratio requirement, as well as the one for production. 15. The implementation of the involute tooth yielded a standard gear design that provides a constant speed ratio . 16. Various speed ratios are obtained by holding or clutching various combinations of elements of the planetary train. 17. If the average stress-to-speed ratio of the sample at the crystal surface ( the load impedance, " Z" 18. STV applies region-based pricing and the price / speed ratio is largely dependent on the different service plans. 19. This improves the bat's Bat Performance Factor ( BPF ) or Ball Exit Speed Ratio ( BESR ). 20. Height, weight, and speed ratios rule in that system; Armey came up under one based more on production.
