A man expends 100j of work to move a box up a inclined plane. the amount of work produced is 80j. what is the efficiency of the machine?
80%
How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
What is the formula to calculate percent efficiency?
(work out/work in) x 100
What is the efficiency is the output work is 12000 and the input work is 15000?
Efficiency as a percent is output/input * 100%12000/15000 * 100% = 80% efficiency which makes sense, because it takes more work (input) than it give out (output). So the efficiency should be less than 100%.
What is a percentage of work in to work out?
efficiency

If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
How can convert efficiency to percent?
Work done = (force * distance)>Efficiency (%) = (Work done output / Work done input) * 100
What is the formula to calculate percent efficiency?
(work out/work in) x 100
What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
A levers efficiency is 95 percent The work in is 95 J What is the work out?
To find the work out, you can use the formula for efficiency: Efficiency = (Work out / Work in) * 100. Given that the efficiency is 95%, you can rearrange the formula to find Work out as follows: Work out = (Efficiency / 100) * Work in. Substituting the values, you get Work out = (0.95) * 95 J = 90.25 J.
If the output work of a simple machine is than input work the machine is said to have less than 100 percent efficiency?
No, a simple machine with less output work than input work is said to have less than 100 percent efficiency. Efficiency is a measure of how well a machine converts input work into output work, with 100 percent efficiency meaning that all input work is converted to useful output work.
What is the formula for the percent efficiency of a pulley?
The formula for the percent efficiency of a pulley is (output work/input work) x 100%. It compares the output work (work done by the pulley) to the input work (work done on the pulley) to determine how efficient the pulley system is in transferring energy.
The ratio of output power to input power in percent is called a conductivity b efficiency c work d horsepower?
B.) efficiency
What of the machine compares the output work to the input work and is expressed as a percent?
That's the machine's "efficiency".
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.
