That's the machine's "efficiency".

Why does cardiac output of a 70-year- old person often decrease by 75 percent?
No
What does a leverage ratio of 1.8 mean?
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.
What is a tabe organizing the input rule and output of a fraction called?
It is a function with fractions as output.
What are the differences between input and 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?
What is the ratio of output to input?
efficiency
What in a machine compares the input and output force?
That is called the mechanical advantage.
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.
The mechanical what of a machine compares the input force with the output force?
Mechanical efficiency
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.
If the work on a machine equal the output work the machine is said to be 100 percent effentient?
Yes.
How the output work compares to the input work in a machine?
I would say that the output would be less. What would you think? Actually it matters what machine your talking about but hopefully ur output work would be more then your input work because that would mean the machine is doing more. This would mean its more efficent
Efficiency compares energy output with?
Output force
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!!!
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.
