Why should IMA and AMA be the same?

The Actual Mechanical Advantage AMA is equal to: 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.

Why is the work done by a machine always less than the work put into it?

Efficiency is the percent of work put into a machine by the user (input work) that becomes work done by the machine (output work). The output work is always less than the input work because some of the input work is used to overcome friction. Therefore, efficiency is always less than 100 percent.

What is the difference between IMA and AMA?

The AMA of a simple machine is the ratio of output to input forces. The IMA is the ratio of input distance to output distance.

Why is it that the efficiency of a machine is always less than 100\%?

The percentage of the work input that becomes work output is the efficiency of a machine. Because there is always some friction, the efficiency of any machine is always less than 100 percent.

Why is the actual mechanical advantage AMA a force multiplication factor?

Why is the actual mechanical advantage (AMA) a force multiplication factor? Actual Mechanical Advantage (AMA) is the ratio of the output force over input force. The experimental mechanical advantage is called as AMA because some of the energy is lost due to friction.

Why is the actual mechanical advantage of a machine always less than its ideal mechanical advantage and why can no machine be 100\% efficient?

How does the actual mechanical advantage of a machine compare to its ideal mechanical advantage? Because of friction, the actual mechanical advantage of a machine is always less than the ideal mechanical advantage. Why is the efficiency of a machine always less than 100\%? Because there is always some friction.

How is actual mechanical advantage determined?

The actual mechanical advantage (AMA) is the mechanical advantage determined by physical measurement of the input and output forces. Actual mechanical advantage takes into account energy loss due to deflection, friction, and wear.

What is the difference between the actual mechanical advantage and the theoretical mechanical advantage of any machine?

The theoretical mechanical advantage of a system is the ratio of the force that performs the useful work to the force applied, assuming there is no friction in the system. In practice, the actual mechanical advantage will be less than the theoretical value by an amount determined by the amount of friction.

Why is the ideal mechanical advantage of a machine always greater than the actual mechanical advantage of a machine?

The ideal mechanical advantage of a machine reflects the increase or decrease in force there would be without friction. It is always greater than the actual mechanical advantage because all machines must overcome friction.

How does ideal mechanical advantage differ from actual mechanical advantage?

The actual mechanical advantage of a machine reflects the increase or decrease in force achieved by the machine. The ideal mechanical advantage of a machine reflects the increase or decrease in force there would be without friction.
