Physics of Cycling :: physics sport sports cycle bicycle

almost the entire spot of cycling is based on physics. Some aspects atomic number 18 obvious, like contortion and other basic jams, although others do non generate to mind as easily. Things like aerodynamics atomic number 18 playing an increasingly big role in the mutant, along with other things like damped harmonic motion (think mountain rhythm suspension), and efficiency. A lot of the detailed things would be beyond this paper, further the basics, which are the most import parts, will be talked about.Torque is what makes the swans on the bike go round. Great research has been but into the sport in order to figure out how to increase the torque applied by the passenger to the bum wheel, wile decreasing the torque required to make the wheel turn. Torque is produced the rider using a device called a crank.The torque in the series of parts that obtain the bicycle forward (called the drive train) is dependant on the size of the chain of mountains sinker (the large gears mounted on the crank) being used, and the size of the rear sprocket wheel being used. When the chain is on the smaller chain ring, the force through the chain must be greater because the chain ring is closer to the axis of rotation and must apply a larger force to equal the torque produced by the pedals.Likewise, if a larger cog is used in back on the wheel, an larger torque is exerted on the wheel, and so produces a larger forward force at the tire. These higer-torque gears are good for climbing, where large forward forces are need at broken speeds, but for flats and downhills, different gearing is needed, because the lower gearing does not return much forward rotation (the rear wheel will not rotate as much for a single stroke of the pedal). power point of the drive train on a bicycle. The smaller the gear on the crank combined with a large gear on the wheel will produce large amounts of torque and large forward forces. exercise and PowerAlthough torque does have a lot to do with the bike and how it works, professionals and people in the know dont usually refer to torque the rider applies to the wheels. Usually, theyll talk about power. This makes much more sense, because cycling, in general, is a sport that requires you exert yourself for a relatively long amount of time, instead of ripe trying to exert the largest force you can (this isnt weight lifting).
