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 WebJul 14, 2024 · When the ideal mechanical advantage (IMA) is compared to actual mechanical advantage (AMA) in the real world, the value of the ideal mechanical advantage (IMA) is always larger than the actual mechanical advantage (AMA) because some of the effort are used to overcome frictional force and the efficiency of all machines is usually …

IMA is equal to the AMA See answers Advertisement cool2781 Are you sure! Becuase I dont want to get this one wrong! Advertisement AL2006 Choice-B is the true one. Advertisement WebThe differences between the three types of levers, is the location of the fulcrum to the input force and output force. Regardless of the type of lever, they all use the same equations to find AMA and IMA. The general formula for the actual mechanical advantage (AMA) of levers: AMAlever = Fo (output force) Fi (input force) also written as AMA ... florida flights to orlando
In a real machine, the AMA is always ______ the IMA.
WebEfficiency in real machines will always be less than 100 percent because of work that is converted to unavailable heat by friction and air resistance. Wo and W can always be calculated as a force multiplied by a distance, although these quantities are not always as obvious as they are in the case of a lever.
