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.

The efficiency of a real machine?

Efficiency is equal to the ratio of work input to work output; for an ideal machine this ratio is equal to 1 or 100%. 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 the machine.


What is the efficiency of a machine that requires 100 joules of input energy to do 35 joules of useful work?

The machine efficiency is 35 percent (35/100).


What is the maximum efficiency of a machine?

The maximum efficiency of a machine is 100%, which means that all input energy is converted into useful output energy without any losses. However, achieving 100% efficiency is practically impossible due to factors such as friction, heat loss, and other inefficiencies in real-world systems.


What is the efficiency of a machine that miraculously converts all the input energy to useful output energy?

The efficiency of such a machine would be 100%, as all the input energy is converted to useful output energy without any losses. This would be an ideal scenario but is not practically achievable due to factors such as friction, heat dissipation, and other forms of energy loss in real-world machines.


How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?

If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.


Why a normal machine could not have the mechanical efficiency of 100?

Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.


Can a machine's efficiency can be greater than 100 percent?

nope, efficiency o fa machine cannot be greater than 100%...theoretically it shows sometime that efficiency of a machine can be 100%, but practically it cannot be possible as there is some loss of energy is always involved in different ways.


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.
