Equals the output work divided by the input work?
TomonnoCheeksgp8705
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.

Why is the output work always less than the input work for a real machine?
because output work is input work divided by two
Type of machine in which work input equals work output?
Any machine that is 100% efficient. (None exist.)
Why is the mechanical advantage of a simple fixed pulley always 1?
Because the input work equals the output work
What means work output divided by work input?
input force x input distance > output force x output distance -Novanet
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
Why is the output work always less than the input work for a real machine?
because output work is input work divided by two
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)
The work output of a machine divided by the work input is the?
efficiency.
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.
All simple machines ideally work on the principle that?
ANSWER: work input equals work output
If the output work of a simple machine equals the input work the machine is said to have efficiency.?
In that case, the efficiency is said to be 1 - or equivalently, 100%.
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.
Type of machine in which work input equals work output?
Any machine that is 100% efficient. (None exist.)
