MACHINE
an apparatus using mechanical power and having several parts, each with a definite function and together performing a particular task.
Following are the formula for defining relation between power , force, distance and time.
Machines became part of our daily lives. Machines help us to reduce efforts required to do the work. All machines are based on the combination of ‘simple machines’. A simple machine is a mechanical device that changes the direction or magnitude of a force. Scissors, brakes, pulley, gears, inclined plane, screw etc. are the examples of simple machines.
Following are the formula for defining relation between power , force, distance and time.
Power = work / Time
= (force X distance) / Time
= force X speed
Power = force X speed
Work = force X distance.
Work = force X distance.
