Some wheels and axles move together as one piece and act as simple machines. If you apply a turning force on the outside of the wheel, then there is a much greater force applied to turning the axle. An example of this type of wheel and axle is a water wheel. With a water wheel, the water pushes on the wheel and the wheel
The six simple machines are pulleys, levers, wedges, inclined planes, screws and wheels & axles. Compound machines have two or more simple machines that when used together make work easier. A pulley is a variation of a wheel and axle in which a rope or cord is stretched over a wheel to make it rotate as the rope is pulled.
The simple machine shown in Figure 9.8 is called a wheel and axle. It is actually a form of lever. The difference is that the effort arm can rotate in a complete circle around the fulcrum, which is the center of the axle.
In Fig 2.1 is shown a simple wheen and axle, in which the wheel A and axle B are keyed to the same shaft. A string is wound round the axle B, which carries the load W to be lifted.
The wheel and axle is made up of two circles: the smaller one is the axle and the larger one is the wheel. Every time the wheel is turned, the axle turns, too.
Simple Wheel and Axle A simple wheel and axle is shown in Fig. 4. The load is applied to the smaller diameter axle and the effort to the wheel. The wheel and axle ropes are wound in opposite directions. Figure 4 Wheel and Axle If the radius of wheel = R (diameter = D) radius of axle = r (diameter = d)
This document provides 30 practice problems involving calculations with various simple machines, including levers, wheel and axle, pulleys, inclined planes, wedges, and screws. The problems require sketching and annotating diagrams of the described simple machine systems and using static equilibrium equations to calculate values like mechanical ...
