The wheel and axle is a simple machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other. The wheel and axle can be viewed as a version of the lever, with a drive force applied tangentially to the perimeter of the wheel, and a load force applied to the ...

The force amplification, or mechanical advantage, is equal to the ratio of the two forces ( W: F) and also equal to the ratio of the radii of the two gears ( R: r ). For raising weights the wheel and axle has large- and small-diameter drums with ropes wrapped around them in place of the gears. The weight being lifted is attached to the rope on ...

Jan 18, 2022 · There are two basic kinds of wheel and axle discussed below with examples in real and everyday life. 1. Force Applied on the Axle. In this type, the force is applied to the axle and transmitted to the wheel, rotating rapidly. Examples: Bicycle, car tires, Ferris wheel, electric fan, analog clock, and winch. 2.
Differential (mechanical device) Differential unit for a rear-wheel drive car, built by ZF c.2004. Differential gears (in yellow) in a punched tape reader, built by Tally c. 1962. A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others.
