any of various elementary devices considered as the elements of which all machines are composed and including the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw
a device for overcoming resistance at one point by applying force at some other point
a device for doing work that has only one part
a device that acts to increase or decrease the amount
a device that either multiplies or redirects a force
a device that makes work easier
a device that multiplies, divides or changes the direction of the applied force for the purpose of moving a load
a device that reduces the effort to do work
a lever, inclined plane, pulley, and wheel and axle
a machine from which no part can be removed without destroying it as a machine
a technological tool that makes work easier to do, but does not need electricity to work
A machine that requires only the force of a human to perform work. The six types are: the lever, the wheel and axle (including the gear), the pulley, the inclined plane, the wedge, and the screw.
The simple machines are the lever, pulley, and inclined plane, along with their most basic modifications, the wheel and axle, wedge, and screw. A complex machine is a machine made up of two or more simple machines.
something that changes the direction or size of force to make work easier Hand trucks and ramps are simple machines.
In physics, a simple machine is any device that only requires the application of a single force to work. Work is done when a force is applied and results in movement over a set distance. The work done is the product of the force and the distance.
