for example a cyclist uses gears to intensify the power output of his pushing on the pedals. Gears have many properties, one of which is the speed ratio, often known as gear ratio. This is the ratio of the turning speed of the input gear to that of the ...
calculate the gear ratio as 40/20, which simplifies to 2/1, or 2:1. (The tooth count on the driven wheel always goes on top of the fraction or first in the ratio). This tells you that, for every rotation of the driven wheel, the driver wheel makes two rotations. Similarly, a rat...
Height:taller riders are less aerodynamic than short riders, so the shorter rider will go faster if two riders are holding the same wattage and everything else is equal (weight, frame/wheels, etc).Read “How Rider Height Affects Speed” for specifics. Virtual Bike Choice:the frame and wheel...
The nose-down tendency will increase the airplane’s stall speed and make cruise flight much slower. If the CG is located too far aft, the airplane will have a nose-up tendency. This typically is the most dangerous situation. The aircraft will have a noticeably higher cruise speed, but the...
Progressive pitch improves performance in high-speed applications. Propeller pitch determines the final gear ratio between the engine and the water. A boat should be "propped" to operate within its wide-open throttle (WOT), which can be found in the motor specifications or the owner's manual....
N1/N2 = gear ratio T1 = motor torque T2 = output torque N1 = motor speed N2 = output speed This is basic to gearboxes or friction drives. Upvote 0 Downvote Sep 13, 2005 #9 sacem1 Mechanical Nov 26, 2002 186 I don't think the problem is really well described: If the motor...
