Think of work as the transfer of energy. What you are proposing would violate the Law of Conservation of Energy. Simply put, you can't get something from nothing. You can't magically convert 1 dollar into 2 dollars, you can't convert one liter of water into two liters. In the case of energy, it is similar: you can't convert one joule of energy into two joules of energy.
What else can I help you with?
Explain why the output work for any machine cant be greater than the input work?
The output work from a machine cannot be greater than the input work because of the law of conservation of energy. Energy cannot be created or destroyed, only transformed from one form to another. Therefore, the output work of a machine cannot exceed the input work that was initially put into it.
Why cant a machine put as much energy out as you put in?
Losses of energy within the machine- some of the energy is used up by friction, and converted to heat. There is also the matter of efficency of a machine. The less efficent, the more power you must put in to get the same output.
What are the limitations of sequential circuits?
it can represent only the finite state machine.In such a machine an arbitrarily long sequence of input symbols is bound to create a periodic output with a period not more than the number of states.hence computations that need to remember an arbitrary number of past input symbols cant be implemented by seq machines
Why cant a machine be 100 percent efficent?
The question is a little vague, but if I understand correctly, you're asking why a machine doesn't release as much energy as you put in to it. The reason for this is that energy is very unpredictable. For instance, if you add 1000 W into an electric kettle, not all the energy will go into heating the water. Some of the energy gets lost in the wires, some of the released heat might go into the air, some of the water might boil, etc. The same thing applies for all other machines.
Why cant a third class lever have a mechanical advantage of 1 or more?
A third class lever has the effort force between the fulcrum and the load, which results in a mechanical advantage of less than 1. This means that the input force needed to lift the load is greater than the load itself, making it mechanically disadvantageous for lifting heavy objects.

Why the output work for any machine cant be greater than the output explain?
-- The output work can't be greater than the output because they are, by definition of the terms, the self-same quantity, and consequently can be neither greater not lesser, but must at all times remain identical. -- The output work can't be greater than the INPUT ... unless additional energy is supplied inside the machine ... because total energy of a system is conserved, and cannot be created ex nihilo.
The comparison between output work imput work is?
Work input is how much work you put into a machine and work output is the work done by the machine according to how much work you put into it. You will never get more work out of a machine than you put into it. The efficiency of a machine is how much useful work you got out of the machine compared to how much you put in (expressed in a percent). Efficiency = Useful Work Output ÷ Work Input
What is an open loop?
Output is obtained for a given input and we cant control the output my means of any feedback loop control to the input

Photograph and picture the same?
no, because the photography is the input or the processing of how we see the output or the pictures, but without photography we cant see the images that we produce..
Why cant machine convert all their input into useful work?
There are a number of reasons why machines cannot convert all of their input into useful work. This is because they were made by humans and have a margin of error.
What is terminal device?
A terminal is a text-based user interface for interacting with computers. U cant talk to a computer machine . Machine listen to u with the help of a terminal . Terminal takes input and shows output. The most commom example is Monitor for Output and Keyboard for Input..
Is a cell phone a input or output device?
a phone is either it can be or it cant bcause you can talk into it and someone can talk out of it .
Can you get output current greater than input current?
No, we don't find the output force of a system is greater than its input. We've never seen this. There are losses associated with any system, whether they be mechanical, thermal or other. That prevents a situation where we can get more energy out of a system than we put in. We don't know all there is to know about physics, but we know a lot. If we knew how to get more energy out of a system than we put into it, we'd have applied that to generate electrical power. Consider how we provide electricity ot the power grid now and think it through to confirm the idea that we don't know of a way to get more energy out of a system than we put in. Perpentual motion isn't something we've realized, either.
Why power amplifier are called as large signal amplifiers?
in general the CE amplifiers are called low-signal amplifiers as they use only small values of voltage as a source of input which cant be used in practical purposes, whereas power amplifiers deal with practical values of input and output voltages
