No. That would violate Conservation of Energy, so it follows that it isn't possible.

Is a machine physically possible that has an efficiency greater than 100 percent?

Not if the laws of physics - specifically thermodynamics - are correct.


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.


Can a machine be more than 100 percent efficient?

100% efficiency would mean that the machine is able to transform energy from one form into another without any loss of energy from the system in the process. For it to have greater than 100% efficiency, it would have to somehow generate additional energy, not contained in the system, in the process, and this is not possible.


What would a machine that had 100 percent mechanical efficiency be called?

an ideal machine


What machine on earth has the greatest percentage of efficiency?

Perhaps an electrical AC transformer can have 99 percent efficiency. A loudspeaker can have only 1 percent efficiency.


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.


What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?

The mechanical efficiency of this machine is 30 percent.


What is mechanical efficiency in science?

mechanical efficiency is the percent of the energy that you put into a machine that was transferred to the load.


What is percent efficiency?

it is the amount of work that can be done. a machine can use 300,000 J of energy but it only uses 263,000 J. that is percent efficiency.


What of the machine compares the output work to the input work and is expressed as a percent?

That's the machine's "efficiency".


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.


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).
