Can you make the work output of a machine greater then the work input?

Verified answer
No - that would violate Conservation of Energy. So far, there is no known process that violates Conservation of Energy, and it doesn't seem likely that one will ever be found.

∙ 6y agoNo. And you cannot make it greater THAN the input, either.

What is the work input for a machine?
The energy that is used to make the machine work.
What machines can change the direction of a force?
Well, its not that hard: Some machines help people do work by changing the size of the force needed. Have you ever tried opening a door by turning the shaft instead of the handle? Not as simple. It takes less force to use the handle instead of the shaft. If a machine (doorknob attached to shaft) allows you to exert less force, you must apply that force over a greater distance. the complete and total amount of work done remains the same, whether its by machine or not. Because a machine does not change the amount of work to be done, less force must mean greater distance. So: Machine=less force BUT greater distance!
How can you make the work output of a mcahine greater than the work input?
That is not possible. For more information, do some reading on the "Law of Conservation of Energy". More specifically, no cases are known of this law being violated, and no mechanism is known that might make this even remotely possible.
Why can't the output work be greater than the input work?
When you input force to do work, the output work cannot be greater than what isput in, because work is energy, and energy is 'conserved'. That means it can't becreated out of nothing.If you had a box that could put out more work than you put in, you would be kingof the world. Once you get the box going, you could take off enough of the outputwork to put back into the input and keep it going, and you'd have some left overthat could be used to generate electricity, run a car, lift a load, cut wood, cook afish, heat a room, power a boat, weave a rug, boil water, plow a field, etc. Andyour box could do any of these things without a single drop of oil or lump of coal!It's called "perpetual motion". It's fundamentally impossible, but scam artists forhundreds of years have been able to shake millions of dollars out of investors whocould be convinced that you can get more work out of a machine than you put it.YOU CAN'T MAKE THE WORK OUT PUT GREATER THAN THE INPUT BECAUSE FRICTIONS ALWAYS PRESENT SO YOU WILL NEVER HAVE 100% EFFECIENCYAll machines are limited by the Laws of Thermodynamics.The Carnot cycle shows the maximum efficiency of any process for a given temperature. Efficiency, (work output:work input), is inevitably reduced by the presence of flaws in operation and or design of the machine. Natural inefficiency factors also play a great part in this reduction: friction, air drag, rusting, etc. There has yet to be a 100% efficient machineThat's easy to answer with the law of Conservation of Energy ... energy is nevercreated or destroyed, it just gets moved around, a lot like snow in northern Alaska.Put some energy into a machine, and that's the only energy that's available to come outthe other end, unless somebody pours in some more energy in the middle. Energy cannever just magically appear out of nothingness somewhere inside the machine.The output work is less because of what is lost to heat and friction within the machine.The output work is always slightly less than the work input work. This is because some of the work done is used to overcome friction created by the use of the machine. However the work is not lost. The output work plus the work done to overcome friction = the input work. The less work the machine does to overcome friction the greater the efficiency.

No. And you cannot make it greater THAN the input, either.
What changes can a machine make a force?
It can either increase or decrease the output force, as compared to the input force. The output force may also be equal to the input force.
In a practical machine the power output is the power input?
In any practical machine, the power output is less than the power input. In other words, the efficiency of real machines is less than 1.smaller thanalways
What is a dubbing cord for?
If you want to make an exact copy of a recording from machine "A" to machine "B", a dubbing cord goes from the output terminals of machine "A" to the input terminals of machine "B". The word "dub" means "a copy of" in recorded music.
How do you make an input output table?
You draw a rectangle and then you divide it into to 2 equal parts (split it down the middle). After you do that you label the input side x and the output side y. And now you got an input output chart.
What work is input for a machine?
The energy that is used to make the machine work.
What is the work input for a machine?
The energy that is used to make the machine work.
How do you make a sentence of output?
I enjoyed your input into our discussion; now I've my own output to contribute.
What is the different between the input and the output in science?
do you mean science? input is what you start with, output is what you get. for instance to make scrambled eggs, we input milk and eggs (minus the shells!) to a pan, add heat, stir and we get out tasty scrambled eggs. there are many types of input and output.
Can you make the input shaft turn by turning the output shaft?
yes
Is touch screen input or output?
Both. There's a touch panel that is used to feed information in to the device (input) and a screen underneath the touch panel to display stuff (output). This makes it to be both input and output.
Full-adder using 4 X 1 multiplexer?
its simple......just you have to make truth table of input and output ......then u will notice that output column can be obtaining by just replacing it by third input or negation of it... in some cases output just hav to connect to one or zero input........for the corresponding output
