What equals the work output of a machine?
The work output equals the output force times the output distance. The only way to increase the work output is to increase the work input. You can’t get more work out of a machine than you put into it.
What is the work output and work input?
Work In, Work Out: The work that you do on a machine is called work input. The work done by the machine on an object is called work output. means that less force will be needed for the same amount of work.
Why is output work is not equal to input work?
The output work is always less than the input work because some input work is used to overcome friction. Therefore, efficiency is always less than 100 percent. Efficiency is the percent of work put into a machine by the user (input work) that becomes work done by the machine (output work).
Why the efficiency of a machine is never 100?
A machine cannot be 100 percent efficient because output of a machine is always less than input. A certain amount of work done on a machine is lost to overcome friction and to lift some moving parts of the machine.
How do you find the work output of a machine?
The formula calculating work output is F*D/T, where F is the force exerted, D is the distance and T is the time. The work output of a system is also described as its Power. In order for work to be done, force has to be applied in the direction of the motion.
Why is work output of a machine never equal?
The output work is always less than the input work because some of the input work is used to overcome friction. Therefore, efficiency is always less than 100 percent. The closer to 100 percent a machine’s efficiency is, the better it is at reducing friction.
What is output of a machine?
Work output is work that is done by a machine equals resistance force times the distance through which the force applied. For an ideal machine, the work output is equal to the work input, i.e. the efficiency.
What is the input of a machine?
1. Any information or data sent to a computer for processing is considered input. Input or user input is sent to a computer using an input device.
Why is the output of a machine less than the input?
Why is input work greater than output work?
Which is the correct definition of work output?
In physics, work output is the work done by a simple machine, compound machine, or any type of engine model. In common terms, it is the energy output, which for simple machines is always less than the energy input, even though the forces may be drastically different. What is the definition of input force?
What is the output of a compound machine?
In physics, work output is the work done by a simple machine, compound machine, or any type of engine model. In common terms, it is the energy output, which for simple machines is always less than the energy input, even though the forces may be drastically different.
Why do input and output have to be the same?
As it is physically impossible to create a loss less system so, input always equals to output + losses. input = output + losses. That’s why input has to be always greater that output to make the system work. Why the output are different?
Which is an example of an output on a computer?
Any information that is processed by and sent out from a computer or other electronic device is considered output. An example of output is anything viewed on your computer monitor screen, such as the words you type on your keyboard.
