Correct power calculation
editIn "Relevant Calculations" Power is given by P = F x d / t which is force times speed. For the SI unit Watt, the unit of force is Newton and not kg or even kp (which is a force, but would not give W). However Wingate testers seem just to use their kg masses as force and not multiply by g (9.81 m/s2), which would be correct. Therefore this implies that the brake band has a coefficient of friction of only about 0.1. Apart from other errors: see http://www.unm.edu/~rrobergs/478FranklinWingate.pdf Does anybody know more about this and how to give the formula correctly? The reference https://www.sport-fitness-advisor.com/wingate-test.html used by everybody is clearly physically wrong. Theosch (talk) 18:23, 22 November 2017 (UTC)
- I've now found a reference which explains it nicely and can even be used for WP. The relevant sections of this article need to be adjusted.
