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 work output of a machine never equal to the work input?
It is usually less. The reason for this is that some energy is usually lost (wasted) in the machine.
What in an output force?
In a closed system in the "real world" in which we live, there are losses associated with friction and other actions. These forces "take energy" from the system between its input and output. When we apply force to the imput of a system, some is lost as the force is transferred through that system. That means that the output force we observe will always be a bit less than the input force. A transmission in a vehicle is a classic example of the idea that there are losses between the input and the output of a system. The input from the engine will always be a bit greater than the output at the tailshaft (or axles for a transaxle) due to losses within the transmission.
Is work input always equal to work output?
Yes the only thing a machine changes is force,distance or direction
Why is difficult to increase the efficiency of a machine?
cheese

Why is the work output of a machine never to the work input?
Some work input is used to overcome friction.
Why is the work output of a machin never equal to the work input?
Some work input is used to overcome friction.
What is the difference between an ideal machine and a real machine?
In ideal machine input is equal to output . The efficiency of ideal machine is 100% . In real machine input is not equal to output .The efficiency of ideal machine in not 100% . In ideal machine there is no lose of energy . In real machine there is lose of energy . In real machine there is no friction . While in real machine there is friction .
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

Work output can never be greater than?
Work input.
Is the scanner is input as well as output device?
Scanner can never be an output device! You most understand that scanner, falls into input device that helps to take input from the user into the computer.
An ideal machine would have an efficiency of?
A ideal machine would have an efficiency of 100 percent. For this to be possible, the amount of energy output by the machine would equal the amount of energy input. Because all machines have physical parts, some energy is lost to friction, heat dissipation, or other factors, so no machine can be an ideal machine.
