What is a percentage of work in to work out?
efficiency
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.
How do you calculate efficiency and how is it expressed?
For efficiency, you have to consider the energy or work that you get out of the machine, compared to the energy or work that you put into the machine. Its what you get out, divided by what you put in. By multiplying the result by 100, you should then get the efficiency expressed as a percentage, which is the normal way of describe how efficient a machine or process is. efficiency = (Work out/Work in) x 100 Sometimes you are given the efficiency in a problem, but then have to calculate either the work out or work in, so then its just a case of rearranging the equation above.
The ratio of output work to input work is?
efficiency
What is the work out divided by work in times a 100?
It is the percentage efficiency.
Percentage of work in to work out?
I think it is efficiency.;)
What is efficiency of a simple machine?
Efficiency % = (work out / work in) * 100 (Work = force * distance)
What is the efficiency of a simple machine?
Efficiency % = (work out / work in) * 100 (Work = force * distance)
What is the formula to finding the work output of efficiency?
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.
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.
How do you calculate spring efficiency?
Spring efficiency is calculated by dividing the work output of a spring by the work input. It is expressed as a ratio or percentage, with higher values indicating better efficiency. The formula is: Efficiency = (Work output / Work input) x 100%.
What is a percentage of work in to work out?
efficiency
How do you determine mechanical thermal and relative efficiency?
Mechanical efficiency is determined by dividing the output work by the input work, while thermal efficiency is calculated by dividing the useful work output by the heat input. Relative efficiency is the ratio of mechanical efficiency to thermal efficiency and can be used to compare the effectiveness of a machine in converting input energy to useful work.
Which factor increases as the efficiency of a machine increases?
The output work done by the machine increases as the efficiency of the machine increases. This is because efficiency is the ratio of useful work output to the total work input, so as efficiency increases, more of the input work is converted into useful output work.
What is the mechanical efficiency of a machine that produces 400 joules of work output from work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
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.
