On application of brakes, a cycle comes to a stop due to the friction between
the spokes and the rim of the wheel
the brake-lining and the rim of the wheel
the brake-lining and the saddle
the crankset and the pedal
The application of brakes to stop a cycle is possible due to the friction between the brake-lining and the rim of the wheel.
Two geometrically identical cycle wheels of a bicycle moving due east have different number of spokes connected from center to rim. Rear wheel has 20 spokes and the front wheel has only 10 (the rim and the spokes have negligible resistance). A resistance R is connected between center and rim in each wheel. The current in R will be :
