In a real machine why is the work output always less than the work input?
Every real machine is subject to forces that reduce output. These include actual forces such as friction, or human controlled forces such as imperfect machining. This reduces the output to less than the ideal.
Can the actual mechanical advantage of a machine ever be greater then its ideal mechanical advantage?
In real machines, there is always friction that reduces the efficiency of the machine.This reduces the mechanical advantage because some of the input force has to be used to overcome the force of friction in the machine.To reduce friction in the machine, you could add a lubricant such as oil.
Do real gases behave like ideal gases except at very high temperatures?
Gases behave most ideally at low pressure and high temperatures. At low pressures, the average distance of separation among atoms or molecules is greatest, minimizing interactive forces. At high temperatures, the atoms and molecules are in rapid motion and are able to overcome interactive forces more easily.

What is the real practical cycles and state if it is a base on ideal theoretical cycles?
The real practical cycle refers to the actual performance of thermodynamic cycles, such as the Carnot, Otto, or Rankine cycles, in real-world applications. Unlike ideal theoretical cycles, which assume perfect conditions and efficiency, practical cycles account for irreversibilities, heat losses, friction, and other non-ideal factors that occur in real engines and systems. While these practical cycles are based on the principles of ideal cycles, they often operate at lower efficiencies and have more complex behaviors due to these real-world influences.

How is a real machine and an ideal machine different?
A real machine is a physical device with moving parts that may have friction and energy losses, resulting in reduced efficiency. An ideal machine is a theoretical concept that assumes no energy losses due to friction or other factors, resulting in 100% efficiency. Ideal machines are used for theoretical calculations and comparisons, while real machines consider practical limitations and inefficiencies.
Work input equals work output is what type of machine?
A machine that has work input equal to work output is known as an ideal machine. This means that the machine is 100% efficient, converting all the input work into useful output work without any losses. Ideal machines only exist in theory, as real machines always have some energy losses due to factors like friction and heat.

Why is the actual mechanical advantage of a machine different for a machines ideal mechanical advantage?
The actual mechanical advantage of a machine is usually less than its ideal mechanical advantage due to factors like friction, energy loss, and imperfections within the machine. These losses reduce the efficiency of the machine in transferring input force to the output force. Ideal mechanical advantage is based on the design and geometry of the machine, while actual mechanical advantage accounts for real-world limitations and performance.
Does an ideal machine have an effciency of 100 percent?
No, an ideal machine cannot have an efficiency of 100 percent. This is because some energy is always lost as heat due to factors like friction and resistance. The best an ideal machine can achieve is an efficiency of 100% by having no energy losses.
Why is the AMA of a machine always less than IMA of a machine?
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.
How does a real gas behave most nearly like an ideal gas?
A real gas behaves most like an ideal gas when it is at low pressure and high temperature.
At what conditions does a real gas behave most like an ideal gas?
A real gas behaves most like an ideal gas at high temperatures and low pressures.
Does an ideal machine have friction?
No, an ideal machine is usually considered to be frictionless to simplify calculations and convey fundamental concepts. In reality, all machines have some level of friction, which can reduce efficiency and introduce energy losses.
