ANSI Device Numbers. From Wikipedia, the free encyclopedia. The ANSI Standard Device Numbers[1] [2] [3] denote what features a protective device supports (such as a. relay or circuit breaker). These types of devices protect electrical systems and components from damage when. an unwanted event occurs, such as an electrical fault.
The piston ring speed on the average chainsaw travels 2,500 surface feet per minute. A chain slides across the surface of the sawbar rail at around 5000 feet per minute. The chain is moving at 55 to 60 m.p.h. or a mile per minute (88 feet per second).
Chain, as we all know, is the primary link on our karts between the engine to the rear axle sprocket in sprint racing. #35 chain has been used since karting began, and is still used today. 99.9% of four cycle racers generally use #35 chain. Two cycle racers are probably the greater users of #219 chain.#219 chain primarily started in the European countries. The Europeans use either #219 chain or 8mm chain.Japan as well uses #219.n two cycle racing at indoor events, you can achieve 9 more teeth in the rear by using #219 chain and still have the same outside diameter rear sprocket for ground clearance. If using a 9-81 in #35 chain, your ratio is 9 to 1; the same in #219 chain would be a 10-90, which is 9 to 1 also.
