What else can I help you with?
What is the definition of mechanical efficiency?
Output work divided by input work
Why does value of output always equal income received by the resources that produced the output?
you work an hour at McDonalds for $7.50. You value that hour, right? How much do you value it? You can tell by the income you received: $7.50. Income is the measure of value.
The south would not be able to maintain its agricultural output until it developed a new systemto replace?
Slaves, and the work force they provided
What is the difference between productivity and efficiency?
Business companies often measure productivity by the output produced during a specified time period. Efficiency, on the hand, relates to the quality of work in creating output with less waste and using fewer resources.
Amount of work done divided by the time it takes to do it is defined as?
The average power in that period. Power (watts) = joules/sec
What is the work output of machine divided by the work input called?
That is called the efficiency.
How do you calculate the mechanical efficiency of a machine?
Work output divided by Work input Times 100
What is a a comparison of a machines work output with the works input that is mechanical?
Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical energy.
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.
The output work of a machine compared to it input work is the of the machine?
Output(input), or O(i)
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.
What is the difference between work input and work output?
Work Output is the work done BY a machine. Work Input is the work done ON a machine.
What is the differences between work input and work output?
Work Output is the work done BY a machine. Work Input is the work done ON a machine.
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 is a comparison of a machine's work output and work input?
Output is always greater than input. The output is multiplied from input.
What is a comparison of a machines work input and work output?
mechanical efficiency
If the input work on a machine the machine has blank efficiency?
If the input work is processed by a machine and no output work is produced, the machine is considered to have zero efficiency. This means that the machine is not effectively converting input work into useful output work.
