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.

Explain how much efficiency of an ideal machine compares with the efficiency of a real machine?
An ideal machine has, by definition, an efficiency of exactly 100%, which means that absolutely none of the energy it consumes is wasted when converted to power (energy per unit of time), hence the name "ideal". A real machine, however, will never reach an efficiency of 100%, as there will always be at least a tiny bit of energy that is lost to the environment. This is because it is practically impossible to create a perfectly closed system in which no energy can leak out. It is possible, however, to build very efficient systems and machines, although this depends on just how well they are made. Therefore, the efficiency of a real machine is quite variable, going easily from 10% to 98%, depending on its quality. A simple example is that of ordinary household voltage transformers, which generally have efficiencies of around 80%; and of high grade power plant transformers, which have efficiencies of around 98%.
How is a real machine like an ideal machine?
A real machine is like an ideal machine in that there are no massless chains or frictionless bearings. The parts of an ideal machine are rigid and weightless.
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.
Why doesn't any system have 100 percent efficiency?
frictionIn real machines, as opposed to ideal machines, there is always friction that reduces the efficiency of the machine. Lubricants like oil can be used to reduce friction and improve efficiency.
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 do you multiply to find the total mechanical advantage?
The "Ideal Mechanical Advantage" of a simple machine isIMA = output force /input force . To find the 'actual' or real-world mechanical advantage,multiply the IMA by the machine's efficiency.
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.
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.
