The output force of a rake is greater than the input force?
Yes, the output force of a rake is greater than the input force.
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.
Can you make the work output of a machine greater then the work input?
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.
Can you make work output of a machine greater then the work input?
No. And you cannot make it greater THAN the input, either.
What is the difference between mechanical advantage and Efficiency?
A mechanism with a positive mechanical advantage is one in which the input force is greater than the output force. This is compensated for by the fact that the distance moved by the input is greater than the output so that in an ideal machine, the work input (Force*Distance) is the same as the work output. In real life, though, you always lose some energy - in the form of frictional heat, or sound.A negative mechanical advantage is the opposite. A small distance moved by the input is converted to a large distance moved by the output. But the force in the output is correspondingly reduced.A mechanism with a positive mechanical advantage is one in which the input force is greater than the output force.

Is energy input usually greater than energy output?
The energy input is always greater than energy output.
Is it possible for energy output to be greater than energy input?
No.
Why it is impossible to have output greater than work input?
Whenever we do any work some energy will be converted into any form other than the actual input energy for the work to be done so it is impossible to have the output greater than work input example : some energy will be converted to heat energy due to friction
What are the comparison of energy output with energy input?
Energy output refers to the amount of usable energy obtained from a system, while energy input is the amount of energy required to operate that system. A system is considered efficient when the energy output is greater than the energy input. Conversely, inefficiency occurs when more energy is put into a system than what is obtained as output.
If a machine has a mechanical advantage much greater than 1 how will the output force be in comparison to the input force?
The Output Force Will Most Likely Be Greater Than The Input Force. So "OUTPUT" Is Greater Than "INPUT".
The output force of a rake is greater than the input force?
Yes, the output force of a rake is greater than the input force.
What is a comparison of a machine's work output and work input?
Output is always greater than input. The output is multiplied from input.
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.
Why can't the output work be greater than the input work on the inclined plane?
Then efficiency would become more than one. This leads to the concept of creating energy which is against the law of conservation of energy. If there is a gravitational incline, moving down the plane can give an output of work greater than the "immediate" input, because of the gravitational potential energy. So if you ignored the gravitational potential energy, the output could be greater. If you don't ignore the gravity, then no; you can't create energy, you can only transform energy.
Can you make the work output of a machine greater then the work input?
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.
Can you make work output of a machine greater then the work input?
No. And you cannot make it greater THAN the input, either.
Work output can never be greater than?
Work input.
