They provide many examples so that kids can identify simple machines in their environment in addition to instructions so they can construct them/5. Calculate the mechanical advantage of a wheel (i.e how helpful it is to us): MA= radius of wheel/radius of axle. Discuss what a radius is and how to measure it on a circle.

Point out the wheel and the axle on a bicycle. Divide children into 2 groups and assign each group a bike. Have each group measure their BACK wheel and axle. The wheel and axle is a machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in You are here Everything A wheel and axle is a round disk (the wheel) with a rigid rod (the axle) connected through the centre of the wheel so that when one turns, so does the Size: 5MB.

Simple Machines: Wheel and Axle Wheels and axles are usually circular objects, often a big wheel and a smaller axle, rigidly secured to one another. The wheel and axle will always rotate at the same speed. Due to the bigger circumference of the wheel, the surface of the wheel will turn at a greater speed — and with a greater distance too.

Since the ratio of the wheel diameter to the axle diameter is large, ie d/a, the minimum force F required for movement is proportionately reduced.

The wheel effectively works as a lever, magnifying the force at the axle, and overcoming the limiting value of the friction force F r. Notice also for a given axle diameter a, if the wheel diameter Author: Eugene Brennan. If you ride a bicycle or a skateboard, or if own roller skates, you use wheels and axles.
