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 … Webfrictionless machine would give you. AMA accounts for additional energy needed to overcome friction in real machines. AMA is always less than IMA because all machines are less than 100% efficient. (pp. 299-301) 7.

Did you know?
WebIn any real machine some of the effort is used to overcome friction. Thus, the ratio of the resistance force to the effort, called the actual mechanical advantage (AMA), is less than the IMA. The efficiency of any machine measures the degree to which friction and other factors reduce the actual work output of the machine from its theoretical ... WebApr 3, 2024 · Which of the following describes the efficiency of real machines? A. Efficiency is 100% B. IMA is always larger than the AMA C. IMA is always smaller than the AMA D.

WebNov 29, 2008 · For a real machine this ratio is always less than 1 because some of the work input is used to overcome mechanical friction within the machine which does not contribute to the work output of... 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. Practice Problems
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.
WebApr 27, 2010 · The AMA is equal to the load force (the weight of what you are lifting) divided by the effort force (the # you are looking for). So, for example, if your IMA is 5 and your …
