The efficiency of a simple machine is defined as the ratio of useful work done by machine (output work) to the total work put into machine (input work). The ratio of the load to the effort in a simple machine is called mechanical advantages or actual advantage of the machine. LOAD FORCE * distance (upward) = effort force * DISTANCE (downward) 200 lbs * 1 foot = 25 lbs * 8 feet. or. 200 lbs * 1 foot = 100 lbs * 2 feet. The key, therefore, is to trade force for distance. You can lift the 200 pound load a short distance (1 foot upward) by exerting a smaller force over a larger distance. 1. …… work-life balance 2. …… overtime 3. …… a best-selling book 4. …… an advantage 5. …… a concept 6. …… to fade 7. …… freedom 8. …… mobility.
