The efficiency of a ramp is 75 percent If the amount of work input is 240 J what is the amoun t of useful work output?
The formula for percent work efficiency is:
percent efficiency = (work output/work input) x 100
To find the answer to this question, you just need to plug the given values into the formula. The problem tells you that the work input is 240 J and the percent efficiency is 75 %, so
75 = (work output/240) x 100
Now, solve for work output:
-first divide by 100
.75 = (work output/240)
-then multiply by 240
180 J = work output (in units of joules because work is measured in joules)
And there's your answer. Hope this helped!
What else can I help you with?
The efficiency of a ramp is 75. If the amount of work input is 240 J what is the amount of useful work output?
The amount of useful work output can be calculated by multiplying the work input by the efficiency. In this case, 240 J * 0.75 = 180 J. Therefore, the useful work output is 180 J.
What is the name of the amount of useful energy you get from a system?
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
What is the relationship between efficiency useful energy output and total energy output?
Efficiency is the ratio of useful energy output to total energy input. A higher efficiency indicates that a greater proportion of the total energy input is being converted into useful energy output. Therefore, as efficiency increases, the amount of useful energy output relative to total energy output also increases.
What do you need to know to calculate the efficiency of a machine?
To calculate the efficiency of a machine, you need to know the amount of useful work output produced by the machine and the amount of total energy input supplied to the machine. Efficiency is calculated by dividing the useful work output by the total energy input and multiplying by 100 to express it as a percentage.

How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
How is energy efficiency determined?
Energy efficiency is typically determined by the ratio of useful energy output to total energy input in a system. It can be quantified by calculating the efficiency percentage, which is the amount of useful energy produced divided by the total energy input multiplied by 100. The higher the percentage, the more energy efficient a system is.
How is the efficiency of a compound machine calculated?
The efficiency of a compound machine is calculated by dividing the output work of the machine by the input work. Mathematically, it can be expressed as Efficiency = (Output work / Input work) * 100%. It gives a measure of how well the machine converts input work into useful output work.
How is the efficiency of a machine calculated?
Efficiency = useful output power / input power
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 relationship between an input work and useful output work?
The relationship between input work and useful output work can be represented by efficiency. Efficiency is the ratio of useful output work to input work. A higher efficiency indicates that a larger proportion of the input work is converted into useful output work, while a lower efficiency suggests that more of the input work is wasted or converted into non-useful forms.
