Why is the output work always less than the input work for a real machine?
because output work is input work divided by two
Equals the output work divided by the input work?
All machines lose some of the input force applied to them as a result of friction and other forces. The efficiency of a machine refers to how much of the input work is converted to output work by the machine. You can find the efficiency of a machine by dividing the output work by the input work. Because the output work will always be smaller than input work, efficiency will always fall somewhere between 0 and 1, with 1 being a machine that has as much output as input work (not possible in the real world) and 0 being a machine that is totally useless because none of the input work is converted to output work.
What is the difference between actual and ideal mechanical advantage?
the equation of mechanical advantage isFout (force, output)divided byFin (force input)the equation for Ideal mechanical advantage isDin (distance, input)divided byDout (distance, output)hope this helps a bit
How does an output work?
how does input device work
How input work and output work computed on each type of simple machines?
(Output work) + (friction losses) = (input work) on any type of machine.
Why is the output work always less than the input work for a real machine?
because output work is input work divided by two
The work output of a machine divided by the work input is the?
efficiency.
How do you find the mechanical efficiency of a pulley?
you have to do: work (output) divided by work (input) = F x d (output) divided by F x d (input)
What is defined as input work divided by output work?
-3/-45
What is the definition of mechanical efficiency?
Output work divided by input work
What is the work output of machine divided by the work input called?
That is called the efficiency.
How do you calculate the mechanical efficiency of a machine?
Work output divided by Work input Times 100
What is a a comparison of a machines work output with the works input that is mechanical?
Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical 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.
What is the definition of output and input work?
Work Input- The work done on a machine as the input force acts through the input distance. Work Output - The work done by a machine as the output force acts through the output distance (What the machine does to the object (dependent on the force) to increase the output distance).
