Some examples of compound machines include scissors, wheelbarrows, lawn mowers and bicycles. Compound machines are just simple machines that work together.Know More
Scissors are compound machines because they contain both a wedge and a lever. Bikes contain pulleys, screws, levers, wheels, axles and inclined planes.
A simple machine is a device or mechanism that changes force. Levers are simple machines that output force from a pivoting point. There are three kinds of levers used in simple and compound machines. They are hammer-type, wheelbarrow type and arm.
Pulleys are another simple machine used to make compound machines. Pulleys work by changing force due to the rotation of a pulley wheel. The wheel and axle is also a simple machine that is simply a pulley attached to a shaft. A car steering wheel and a Ferris wheel are good examples of wheel and axles.
Inclined planes redirect and redistribute horizontal force into vertical force and a wedge is two inclined planes which are back to back. Screws are used in compound machines and are merely inclined planes wrapped around a small cylinder. All of these simple machines can go into making compound machines. Some compound machines only use two while others use a variety of simple machines.Learn more about Motion & Mechanics
Examples of six simple machines include windmills, slides, chisels, drills, blinds and seesaws. A windmill is a wheel and axle, slides are inclined planes, a chisel is a wedge, a drill is a screw, blinds are pulleys and a seesaw is a lever. Simple machines allow humans and animals to do work more easily by lessening the amount of force needed to move objects.Full Answer >
A compound machine is made by combining two or more simple machines. Scissors is a compound machine because it's a combination of a wedge and a lever, which are both simple machines. The cutting edge of scissors is a wedge and the cutting force comes from a lever.Full Answer >
A compound pulley, sometimes referred to as a block-and-tackle system, is a mechanical arrangement of pulleys that permits a trade-off of applied force for distance, according to HowStuffWorks. By slinging rope over and through a system of wheels, a compound pulley permits weights to be lifted and pulled with the application of relatively little force, saving energy and reducing the power needed to accomplish work.Full Answer >
A machine is any device that transmits mechanical energy or power into useful work. The simplest machines redirect an applied force or convert kinetic energy into potential energy. More complicated machines are powered by electricity or fuel and use moving parts and electronic circuitry to complete complex tasks.Full Answer >
