What is the relationship between IMA and AMA?

The relationship between Ideal Mechanical Advantage (IMA) and Actual Mechanical Advantage (AMA) can be understood through the principles of mechanical systems and efficiency. IMA is the theoretical advantage of a machine assuming it is 100% efficient, meaning that all input work is converted into output work without any losses. In contrast, AMA considers real-world conditions where friction, wear, and other inefficiencies can lead to a reduction in the actual output work relative to the input work.

Thus, according to the laws of physics and engineering, the Actual Mechanical Advantage will always be less than or equal to the Ideal Mechanical Advantage. This is because IMA does not factor in loss due to inefficiencies, while AMA reflects the performance of the machine as it operates in practical conditions. Therefore, it's accurate to conclude that AMA is always less than or equal to IMA, which is why this answer holds true in the context of mechanical systems.
