Why is a machine always less than 100 percent efficient?

Machines are never 100% efficient due to factors such as friction, heat loss, and mechanical limitations. Some amount of energy will always be lost during the transfer or transformation process, making it impossible for a machine to achieve perfect efficiency.


Can a machine ever be 100 percent efficient?

No, a machine can never be 100 percent efficient due to various factors such as friction, heat loss, and other sources of energy dissipation. These factors inevitably lead to some level of energy loss, making perfect efficiency unattainable in real-world machines.


Type of machine in which work input equals work output?

An ideal machine that has 100% efficiency will have work input equal to work output. However, in reality, no machine is 100% efficient, and energy is usually lost in the form of heat and other forms of energy.


What work on a simple machine equals the output work the machine is said to be 100 efficient?

If a simple machine is 100% efficient, it means that the input work done on the machine is equal to the output work produced by the machine. In other words, all the energy put into the machine is completely converted into useful work without any energy being wasted.


If the blank work on a simple machine equals the output work the machine is said to be 100 efficient?

Yes, if the input work equals the output work, the machine is considered 100% efficient. This means that all the energy put into the machine is converted into useful work without any energy being wasted.

When the input work on a simple machine equals the work the machine is said to be the 100 efficient?

When the input work on a simple machine equals the work output, the machine is said to be 100% efficient. This means that all the input work has been converted into useful output work, with no energy lost due to friction or other inefficiencies in the machine.


When the input work on a simple machine equals the work the machine is said to be 100 efficient.?

Yes, when the input work on a simple machine equals the work output, the machine is said to be 100% efficient. This means that all the work put into the machine is converted into useful work output without any loss of energy due to friction or other factors.


What is the reason inventors have not been able to invent a machine that is 100 efficient is?

Inventors have not been able to create a machine that is 100% efficient due to the fundamental laws of thermodynamics, particularly the second law, which states that energy transformations are never perfectly efficient and always result in some energy being lost as waste heat. Additionally, factors such as friction, material imperfections, and environmental influences contribute to energy losses. These inherent limitations in physical systems make it impossible to achieve absolute efficiency in any machine.


If the work on a simple machine equals the output work it's said to be 100 efficient?

Yes, when the work input on a simple machine equals the work output, it is considered 100% efficient. This means that all the energy put into the machine is converted into useful work without any loss to friction or other factors.
