That's the machine's "efficiency".
No
It means that an input of 1 unit should result in an output of 1.8 units. The exact output depends on whether the ratio is adjusted for "leakages". In any real machine, some of the force is used up to overcome friction, slippage and so on.
It is a function with fractions as output.
Depends on what you're referring to. Input could be a switch for example, output would be a fan or light coming on. Eating is an input, you can guess what your output is?
efficiency
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 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.
That is called the machine's efficiency.
That is called the machine's efficiency.
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.
In an ideal frictionless system, the work input equals the output and force. Your Welcome!!!
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 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.
The efficiency of a machine is typically expressed as a percentage, representing the ratio of output work/input work.
In an ideal frictionless system, the work input equals the output and force. Your Welcome!!!
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.
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.
