The document discusses the wheel and axle, which is a type of simple machine and lever found in the body. A wheel and axle consists of a wheel attached to an axle so they rotate together, allowing force to be transferred between them. It is typically used to increase force and lift weights, with examples being bicycle wheels, doorknobs, and steering wheels. The mechanical advantage of a wheel and axle is calculated as the ratio of the radius of the wheel to the radius of the axle.

? The wheel and axle is generally considered to be a wheel attached to an axle so that these two parts rotate together in which a force is transferred from one to the other. OR ? A wheel and axle is a lever that rotates in a circle around a center point or fulcrum. ? The larger wheel (or outside) rotates around the smaller wheel (axle). Wheel and Axel-Dr.Paras Bhura PT

? Bicycle wheels, the doorknob, Steering wheels and gears are all examples of a wheel and axle. ? Wheels can multiply distance and speed as well as force. ? Bicycles have large wheels so they go faster. Wheel and Axel-Dr.Paras Bhura PT
