WebJul 2, 2015 · Explanation: The Actual Mechanical Advantage AMA is equal to: AM A = F out F i.n that is, the ratio between the output and input force. The ideal mechanical advantage, IMA, is the same but in absence of FRICTION! In this case you can use the concept known as CONSERVATION of ENERGY. WebFeb 2, 2024 · 3.If a machine was 100% efficient, how would the AMA compare to the IMA? = In any real machine, some of the efforts are used to overcome friction. Thus, the resistance force ratio to the effort (AMA) is less than the (IMA). A frictionless machine would have an efficiency of 100%. Advertisement Webb. Actual Mechanical Advantage has the symbol of AMA. c. Actual Mechanical Advantage can be determined by the following equation: actual mechanical advantage = resistance force AMA = FR effort force FE Efficiency 3. a. A machine multiplies force. How effective the machine is in that is called efficiency. b. chironji processing machine
