IMA is larger than AMA, because the IMA is the FATHER of AMA.

In a geometric setting, the inscribed mean (IMA) is always less than or equal to the circumscribed mean (AMA) due to the inequality in a geometric progression ((a \geq g \geq h)). However, in other contexts or disciplines, this relationship may not always hold true.
Ima is Ideal Mechanical Advantage and Ama is Actual Mechanical Advantage. The difference is that IMA doesn't take into account elasticity or friction and AMA does.
The AMA (Actual Mechanical Advantage) is always less than the IMA (Ideal Mechanical Advantage) of a machine because real machines have inefficiencies such as friction, elasticity, and other losses that reduce the effectiveness of the machine. The IMA is calculated based on ideal conditions assuming no energy loss, while the AMA accounts for these real-life losses.
Ideal Mechanical Advantage can be found using this formula IMA = DE / DR . Ideal Mechanical Advantage is a theoretical calculation, AMA,Êactual mechanical advantage is calculated with this formula, AMA = R / Eactual .
The inclination of the plane affects the effective force required to move an object up the plane, thus affecting the effort force in the calculation of the IMA. The AMA takes into account friction, which is typically present when moving an object on an inclined plane, resulting in a lower AMA compared to the IMA of the same inclined plane.
IMA and AMA are unitless

The AMA (Actual Mechanical Advantage) is always less than the IMA (Ideal Mechanical Advantage) of a machine because real machines have inefficiencies such as friction, elasticity, and other losses that reduce the effectiveness of the machine. The IMA is calculated based on ideal conditions assuming no energy loss, while the AMA accounts for these real-life losses.

The AMA takes into account friction, which is typically present when moving an object on an inclined plane, resulting in a lower AMA compared to the IMA of the same inclined plane.
IMA divided by Length
AMA (Actual Mechanical Advantage) is the ratio of the output force to the input force in an inclined plane, taking into account friction and other real-world factors. IMA (Ideal Mechanical Advantage) is the ratio of the length of the incline to the vertical height, assuming no friction or energy loss. AMA is always lower than IMA due to the effects of friction.
If a machine was 100 percent efficient, the AMA would be equal to the IMA. This is because in an ideal scenario where the machine loses no energy to friction or other factors, the AMA (actual mechanical advantage) would be the same as the IMA (ideal mechanical advantage).
the formulas for simple machines help find the ama, ima, and the efficency
If a simple machine was frictionless, the Ideal Mechanical Advantage (IMA) would be equal to the Actual Mechanical Advantage (AMA). This is because in the absence of friction, all the input work would be completely transferred to the output work without any energy losses due to friction. Therefore, IMA would be equal to AMA, resulting in a more efficient and effective machine.
