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.

The efficiency of a system or device is calculated by dividing the output work by the input work. This ratio provides a measure of how well the system or device converts input energy into useful output energy. A higher efficiency value indicates a more effective use of energy.

If the input work on a machine is equal to its output work the machine has effciency?
If the input work equals the output work, the machine has 100% efficiency, meaning it is able to convert all the input work into useful output work without any losses. An efficient machine is desirable as it maximizes the output for a given input.
What means work output divided by work input?
Work output divided by work input is known as the efficiency of a system. It represents the ratio of useful work output compared to the total work input required to perform a task. A system with high efficiency is able to convert a larger portion of input energy into useful output energy.
When the input work on a simple machine equals the work the machine is said to be the 100 efficient?
When the input work on a simple machine equals the work output, the machine is said to be 100% efficient. This means that all the input work has been converted into useful output work, with no energy lost due to friction or other inefficiencies in the machine.
If the input work on a machine is equal to its output work the machine has efficiency?
Yes, that's correct. Efficiency is a measure of how well a machine converts input work into output work. If the input work equals the output work, then the machine is considered 100% efficient.
What is the formula of each simple machine by getting the work exerted by the machine?
The formula for work exerted by each simple machine is: Lever: Work = Input force × Input distance = Output force × Output distance Inclined plane: Work = Input force × Input distance = Output force × Output distance Pulley: Work = Input force × Input distance = Output force × Output distance Wheel and axle: Work = Input force × Input radius = Output force × Output radius Wedge: Work = Input force × Input distance = Output force × Output distance Screw: Work = Input force × Input distance = Output force × Output distance
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
If the input work on a machine is equal to its output work the machine has effciency?

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%.
What means work output divided by work input?
Work output divided by work input is known as the efficiency of a system. It represents the ratio of useful work output compared to the total work input required to perform a task. A system with high efficiency is able to convert a larger portion of input energy into useful output energy.
How do you calculate the mechanical efficiency of a machine?
Work output divided by Work input Times 100
