The mechanical efficiency can't be over 100% because a type of energy is always lost. For example, it can be lost as heat, sound or even light. When you use a light bulb, it produces light, but heat is lost in the process. See what I mean! In most cases, heat is lost due to friction. the work put out by a machine is always less than the work put into a machine to do the work. Therefore no machine is 100% efficient.
As well....
Efficiency is (power out/power in) x 100.
To get an efficiency of *more* than 100%, the machine must give more power out than is put in.
No machine has ever been demonstrated that does this, and until someone can show this result (power out *more* than power in), we know that any machine has an efficiency less than 100%.

What machine has an efficiency over 95 percent?
Electric induction motors typically have an efficiency of over 95 percent. These motors are commonly used in various applications such as industrial machinery, appliances, and electric vehicles due to their high efficiency in converting electrical energy into mechanical energy.
What does IMA stands for in physics?
IMA stands for "Ideal Mechanical Advantage" in physics. It is a measure of the mechanical advantage of a simple machine, such as a lever or pulley system, in the absence of friction. It is calculated by dividing the distance over which the input force is applied by the distance over which the output force is exerted. A higher IMA indicates a greater mechanical advantage of the simple machine.
What is a example of mechanical efficiency?
A very practical example of mechanical advantage is the use of a "cheater bar." If you find a bolt that is hard to break, simply slip a long pipe or similar object over the handle and it will apply much more torque.
Why cant a machine run forever?
A machine cannot run forever because it will inevitably wear out due to mechanical stress, friction, and temperature changes. As parts degrade over time, the machine's efficiency decreases and eventually it will fail. Regular maintenance can help prolong its lifespan, but eventual wear and tear are unavoidable.
What is the efficiency of a lever if you push 100N over 5m to move 350n over 1m?
The efficiency of the lever can be calculated using the formula: Efficiency = (Output force × Output distance) / (Input force × Input distance). Plugging in the values given: Efficiency = (350N × 1m) / (100N × 5m) = 7/10 = 0.7 or 70%.

What are improvement for engine efficiency for turbine?
The potential for overall improvement is best considered in terms of the efficiencies: thermodynamic efficiency and and propulsive efficiency of the propulsor. Improved fans and propellers could also increase propulsive efficiency by 9+ percent. The aircraft engine turbine engines have considerable room for improvement, with a potential to improve overall efficiencies by 30 percent or more over the best engines in service today, with the potential for improvement of propulsive efficiency being about twice that of thermodynamic efficiency. These engine have considerable room for improvement, with overall efficiencies im- proving by 30 percent or more compared to the best engines in service today. Improve- ments will come from many relatively small increments.
What does it mean when a solar panel has 14.3 percent efficiency.Isn't that a bad thing?
An efficiency of 14.3 percent means that the solar panel converts 14.3 percent of the sunlight it receives into electricity. While it may seem low compared to some newer panels that reach over 20 percent efficiency, 14.3 percent is still considered reasonable and can be cost-effective depending on the specific application and cost of the panels.
Why is energy efficiency of biological systems very low?
Energy efficiency in biological systems is low due to the inherent inefficiency of converting one form of energy to another, such as from chemical to mechanical energy. In addition, biological systems often prioritize other functions, such as growth, reproduction, and maintaining homeostasis, over maximizing energy efficiency. Lastly, evolutionary constraints and trade-offs may limit the optimization of energy efficiency in biological systems.
