Work and machines

Work is the exertion of force through a distance. The formula for its calculation is: work =force x distance. For an example, if 5 newtons of force were applied for 5 meters, the amount of work done would be 25Nm. Mechanical advantage = output force/input force. For example, if a machine takes the force coming in and multiplies it three times, the mechanical advantage would be 3. Read More...
