Machine definition: an apparatus consisting of interrelated parts with separate functions, used in the performance of some kind of work. See examples of MACHINE used in a sentence.
A machine is a mechanical structure that uses electricity or some other form of power source to apply forces and control movement. It does this to perform a specific action. People, animals, natural forces, chemicals, electricity, or heat can drive machines. Early machines were mechanical devices that either humans or animals drove.

A machine is a device that performs work by applying a force over a distance. Simple machines do work against a single load force in a way that increases the output force by decreasing the distance the load moves. The ratio of the output force to the applied force is called the mechanical advantage of the machine.

Energy sources including electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other sources in machines and equipment can be hazardous to workers. During the servicing and maintenance of machines and equipment, the unexpected startup or release of stored energy can result in serious injury or death to workers.
A machine is an object or mechanical device that receives an input amount of work and transfers the energy to an output amount of work. For an ideal machine, the input work and output work are always the same. The six common simple machines are the lever, wheel and axle, pulley, inclined plane, wedge, and screw.
Machines offer more stability to the body, are typically easier to learn, and are more straightforward in their limited use. On the other hand, free weights offer freedom in their use and require the body to provide stability. "Individuals... should consider the specificity of exercise, and how their strength and power will be tested and applied.
The big difference is the feel of the movement. On the machine, it's almost like the path of the moving component is on rails. It can only move in one plane of motion – out, and back again. This is why many people feel machines are safer, and that they are more confident using them. On the barbell free weights bench press, again you aim to ...
Machines can range from simple devices like levers and pulleys to complex systems like robots and computers. Define Machinery. Machinery refers to a collection of machines that are used for a specific purpose or set of purposes. It can include a variety of machines, tools, and equipment that work together to perform a specific function.
An inclined plane and a wedge are two forms of the same simple machine. A wedge is simply two inclined planes back to back. Figure 9.9 shows the simple formulas for calculating the IMA s of these machines. All sloping, paved surfaces for walking or driving are inclined planes. Knives and axe heads are examples of wedges.
A simple machine is a tool, device, or object with few moving parts that help us do work. Simple machines have been in use for a very long time. Early humans used simple machines to push, pull, lift, divide, and crush things. They used simple machines to row rafts over water, build houses, split firewood, and carry heavy items from place to place.
