100 % efficiency,
and the beginning of perpetual motion.

If the input work on a machine is equal to its output work does the machine has efficiency?
If the useful energy output of a system is equal to the energy input, the following calculation can be done:Efficiency = (Useful energy out) / (Energy In)Efficiency = 1Efficiency = 100%Therefore, the machine you describe does have an efficiency value, which is equal to 100%. Very few situations like this exist though, unfortunately.
What is the relationship between energy input and energy output and energy losses whenever transfer of energy takes place?
Input energy = output energy + losses
How is energy efficiency determined?
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
Is work output greater than work input?
No. Work output is less than or equal to work input. Since some energy (work) is lost in most processes, it will usually be less.
When does output force equal input force?
Output force can only equal input force in a system where there are no losses. In the "real world" we live in, there are losses in every system, and that means that output force can nerver equal input force.
What stronger work output or work input?
In theory, work output might be equal to work input; that would be 100% efficiency. In practice, the output of a machine will be less than the input; i.e., some energy will be lost.In theory, work output might be equal to work input; that would be 100% efficiency.

A comparsion of energy output with energy input?
The result (ratio) of such a comparison is called the efficiency. Note that total energy output must be equal to energy input (conservation of energy); however, what is relevant for this comparison is the useful energy output.
What is the Word used when energy input is equal to energy output?
Then you can say the device has a 100% efficiency.
What law of thermodynamics requires the work output of the engine to equal the difference in the quantities of heat taken in and released by the engine?
The first law of thermodynamics requires that the energy input to a system must equal the energy output from a system plus the accumulation of energy in a system. If no energy is accumulating then the energy input is the heat in and the energy output is the work and heat out.
What is the relationship between work input and work output with reference to the law of conservation of energy?
Work output is less than or equal to the work input. This is the law of conservation of energy.
Is energy input usually greater than energy output?
The energy input is always greater than energy output.
If the input work on a machine is equal to its output work does the machine has efficiency?

Total energy input equals equals the useful energy output plus?
Efficiency = ( useful energy output / total energy input ) x 100
