Simple Machines. Simple machines are devices that can make a tough job easier by enabling a person to apply less force or to apply force in a direction that is easier to manipulate. There are six types of simple machines: lever, pulley, inclined plane, wedge, screw, and wheel and axle. Each machine affects the direction or the amount of effort needed to do work. Most mechanical machines, such as automobiles or power tools, are made up of hundreds of parts. However, no matter how complex a machine is, it is composed of some combination of these six simple machines.
A simple machine is a device that acts to increase or decrease the amount of force output by the machine, F o, compared to the force input to the machine, F i. Energy is still conserved. Although a machine like a lever can increase the force, it does not create any new energy, because energy is a conserved quantity.The amount of work input into the machine must equal the amount of work output by the machine (minus some unavoidable energy loss due to friction). W o = W i (ignoring friction losses).he mechanical advantage of a machine is the factor by which the force is increased. A machine that doubles the force has a mechanical advantage of 2. The Ideal Mechanical Advantage (IMA) is the theoretical result achieved when there is no friction.
