Crane at Prague Castle, photo courtesy of handshouse.org “Any sufficiently advanced technology is indistinguishable from magic.” – Arthur C. Clarke “Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. Ideally, the device preserves the input power and simply trades off forces against movement to …

An introduction to physical science covering: matter, chemical properties and reactions, motion, forces, energy, sound, waves, light, and magnetism.

This lever forces stock illustration depicts a simple machine made up of a beam pivoted at a fixed hinge that is used to transfer a force to a load and, in most cases, to provide a mechanical advantage. A lever is a rigid part that can rotate on a single point. The lever is classified into three types based on the locations of the fulcrum, load, and effort. Leverage is also a mechanical advantage obtained in a system. It is ideal for lifting or moving heavy objects. It is a simple but useful…

A simple machine is a non-motorized device that changes the direction or magnitude of a force.[2] Ithat provide mechanical advantage (also called leverage).[3] Usually the term refers to the six classical simple machines part of engineering and applied science. For example, wheels, levers, and pulleys are all used in the mechanism of a bicycle.

Muscles and bones act together to form levers. A lever is a rigid rod (usually a length of bone) that turns about a pivot (usually a joint). Levers can be used so that a small force can move a much bigger force. This is called mechanical advantage.

Mechanical Advantage

One of the basic tools that date from prehistoric times. Simply a beam (lever) is used to move a load with a fulcrum (pivot) and an applied force. The position of the three determines the mechanical advantage. “Give me a place to stand, and I will move the Earth.”, Archimedes, 260BC #lever #archimedes #mechanics
