In a real machine the ama is always
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

WebDec 1, 2010 · A real machine is like an ideal machine in that there are no massless chains or frictionless bearings. The parts of an ideal machine are rigid and weightless. What is the difference between... WebIn physics and engineering, mechanical advantage (MA) is the factor by which a machine multiplies the force put into it. The mechanical advantage can be calculated for the following simple machines by using the following formulas: Lever: MA = length of effort arm ÷ length of resistance arm.
