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 is the work output of a machine never equal the work input?
Because -a small percentage of the input is lost as heat from friction.
How will the work done on the input piston compare to the work done by the output piston in a hydraulic device?
The work done is equal
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.
Is work output always equal to work input?
Yes the only thing a machine changes is force,distance or direction
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.

If a machine's input work and output work are equal it has a high what?
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.
Why is the work output of a machin never equal to the work input?
Some work input is used to overcome friction.
In order for work output to equal work input there must be?
Equalling for work input - now that's a fine idea
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 is the work output of a machine never equal the work input?
Because -a small percentage of the input is lost as heat from friction.
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.
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.
How does friction affect the equality between work input and work output in real situations?
Work Input = Work Output + Work done in overcoming friction.Therefore Work Input > Work Output.
How will the work done on the input piston compare to the work done by the output piston in a hydraulic device?
The work done is equal
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.
