Mathematically, efficiency = (energy output) divided by (energy input) as a percentage. As if we couldn't figure this out for ourselves, one of the laws of Thermodynamics formally tells us "You can't get more energy out than what you put in." Applying this law to the formula for efficiency, it says that the maximum possible efficiency is 100%. However, the next law of Thermodynamics says "You can't even get that much out."
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.
Machine efficiency is typically determined by calculating the ratio of useful output to input. This can be done by comparing the actual output of the machine to its theoretical maximum output under ideal conditions. Factors such as energy losses, downtime, and maintenance can also affect machine efficiency.
The machine would have 100% efficiency if the input work is equal to its output. This means that all the input energy is fully converted into useful output energy without any loss.
As the efficiency of a machine increases, the output of the machine for a given input also increases. This means that the machine can do more work with the same amount of energy input. Additionally, the operating costs of the machine may decrease as efficiency improves, since less energy is wasted.
The efficiency of the machine can be calculated using the formula efficiency = (useful output / total input) * 100%. In this case, the efficiency of the machine would be (67J / 150J) * 100% = 44.7%. This means that the machine is operating at 44.7% efficiency in converting input work to useful output.
In any machine, some energy will usually be wasted. This will reduce the efficiency below the theoretical maximum of 1.0. However, please note that, if the efficiency is above 95% (or 0.95), when rounded to the nearest tenth you will get 1.0.In any machine, some energy will usually be wasted.

The condition for maximum efficiency of a d.c. machine is that VARIABLE LOSSES must be equal to CONSTANT LOSSES i.e., variable losses = constant losses..
The electric space heater. It's the only common machine that's 100% efficient.

Efficiency of any electrical machine is maximum when the load on that machine is such that the variable loss ( copper loss) is equal to constant loss (eddy current loss, hysteresis etc).the same applies to dc machines too.
No heat loss = maximum output. There would be no loss of energy, which is an ideal condition.
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
It is always desirable to run any equipment or device at maximum efficiency for that matter, not only the power transformer. Power transformer maximum efficiency occurs when copper loss is equal to iron loss. (or no load loss equals to load loss). This does not necessariliy mean that maximum efficiency occurs at maximum or full load. Generally the maximum efficiency occurs at relatively less than full load of the transformer.
The plan was carefully orchestrated to insure success. He orchestrated every movement to get the maximum efficiency from the machine.
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
By reducin friction between the machine parts and also by avoiding any sorts of power losses.
