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.

Jun 30, 2011 · Mechanical advantage can be calculated by dividing the effort arm by the resistance arm (MA = EA/RA). In assessing the efficiency of the lever (mechanical advantage), it is important to identify and quantify the components included in the system. This can be achieved by calculating the distance between the axis and the where the force acts.

Overall efficiency is simply the product of volumetric and mechanical/hydraulic efficiency. So continuing with the above example, the overall efficiency of the pump is 0.9 x 0.91 x 100 = 82%. Overall efficiency is used to calculate the drive power required by a pump at a given flow and pressure. Title: New Title Author: New Author Subject: New Subject Created Date: 10/10/2004 8:15:09 PM
