The efficiency of a machine is found by considering the useful energy or work that comes out of it, and dividing this by the work that you put into it. Multiply by 100 to get the answer in terms of percentage.
You should never get more than 100% efficiency, or 100%, since energy will be lost (to heat caused by friction for example).
What else can I help you with?
What is the efficiency of a simple machine?
Efficiency % = (work out / work in) * 100 (Work = force * distance)
What simple machine would you find a fulcrum?
It's a tool
What kind of simple machine is a train?
A train is not a simple machine.
What is a simple machine with 3 simple machines in it?
A complex machine.
What are some questions about simple machines?
Some questions about simple machines include: What are the six types of simple machines, and how do they work? How do simple machines reduce the amount of force needed to perform a task? In what ways are simple machines utilized in everyday life? Additionally, how can the efficiency of a simple machine be calculated?

What is efficiency of a simple machine?
Efficiency % = (work out / work in) * 100 (Work = force * distance)
How does input work and out put work affect the efficiency of a simple machine?
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
Why do you multiply to find the total mechanical advantage?
The "Ideal Mechanical Advantage" of a simple machine isIMA = output force /input force . To find the 'actual' or real-world mechanical advantage,multiply the IMA by the machine's efficiency.
What are the factor that affect the efficiency of simple machine?
Factors that can affect the efficiency of a simple machine include friction, mechanical losses, wear and tear, misalignment, and material properties (such as strength and durability). Proper maintenance and lubrication can help improve efficiency by reducing these factors.
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 happens if you increase the efficiency of a simple machine?
Increasing the efficiency of a simple machine means that it requires less input work to produce the same output work. This results in less wasted energy and ultimately allows the machine to do more work with the same amount of input.
What is the machine efficiency of a machine that produces 400 joules of work output from a work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
If the output work of a simple machine is than the input work the machine is said to have less than 100 percent efficiency?
input
What do you mean by the efficiency of a simple machine is 85 percent?
When the efficiency of a simple machine is 85 percent, it means that 85 percent of the input work is converted into useful output work, while the remaining 15 percent is lost due to factors like friction and heat. This efficiency percentage gives an idea of how effectively the machine is performing its intended task.
Where can you find a simple machine?
Almost everywhere!!!
When the useful energy output of a simple machine is 100 J and the total energy input is 200 J the efficiency is .?
The efficiency of the simple machine is calculated as the useful energy output divided by the total energy input, multiplied by 100%. In this case, the efficiency would be (100 J / 200 J) x 100% = 50%.
