What ratio of output work to input work expressed as a percent is the of a machine.?

The efficiency of a machine is a measure of the ratio of output work to input work, expressed as a percentage. It is calculated as: Efficiency = (Output Work / Input Work) x 100% A more efficient machine will have a higher percentage, indicating that a greater percentage of input work is being converted to useful output work.


The mechanical what of a machine compares the input force with the output force?

The mechanical advantage of a machine compares the input force applied to the machine with the output force produced by the machine. It is calculated as the ratio of the output force to the input force and indicates how much a machine amplifies or reduces the input force.


What compares a machines work output with the work input?

That is called the machine's efficiency.


What compares a machines work output with work input?

That is called the machine's efficiency.


What in a machine compares the input and output force?

A machine's mechanical advantage (MA) compares the input force required to move an object to the output force produced by the machine. This ratio helps determine how much the machine amplifies force to make work easier.


How the efficiency of a ideal machine compares with the efficiency of a real machine?

In an ideal frictionless system, the work input equals the output and force. Your Welcome!!!


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.


The efficiency of a machine is usually expressed in?

The efficiency of a machine is usually expressed as a percentage. The ideal efficiency of a machine is 100-percent.Another AnswerThere are no units of measurement for efficiency, because you are comparing like with like: output power divided by input power.


What unit is used to express the efficiency of a machine?

The efficiency of a machine is typically expressed as a percentage, representing the ratio of output work/input work.


What is a quantity expressed as a percentage that measures the ratio of work output to work input?

The comparison of a machines work output with its work input represented as a ratio is called the efficiency of the machine. In the real world this ratio can never be 1. The reason is that whatever work is input to the machine cannot be converted entirely to output. There are losses due to friction, heat generation and dissipation, air resistance etc. If we could have a machine with an efficiency of 1, we can have perpetual motion. That means that you drive a car up to say 65 mph on the highway and then turn off the engine, you will be going on the highway forever without spending another dime for gas. Turbines in power plants would just have to be started and brought to operating speed and from then on they will run forever.


What is the term for the measurement of how well a machine converts input work into output work?

The term for the measurement of how well a machine converts input work into output work is efficiency. It is expressed as a percentage, with a higher efficiency indicating that the machine is better at converting input work into useful output work.


How the efficiency of an ideal machine compares with the efficiency of a real machines?

In an ideal frictionless system, the work input equals the output and force. Your Welcome!!!
