When a machince is used to perform a task work output is always what than work input?
Work output is always less than work input. This is related to the Law of Conservation of Energy.
Is work input always equal to work output?
Yes the only thing a machine changes is force,distance or direction
How is the efficiency of a compound machine calculated?
The efficiency of a machine is found by dividing the amount of work done by a machine by the amount of energy used by a machine. The answer is then multiplied by 100 to give a percentage.
How do you calculate work input?
That depends a lot on what type of energy is used as input. For example for electrical energy, the input voltage and the input current would have to be measured; multiplying the two should give the input power. (There's actually also a "power factor", but that factor is often close to 1.)
Is the work output always less than the work input when a machine is used to perform a task?
yes
What happens in cells when energy output exceeds energy input?
When energy input exceeds energy output, it means that all the energy taken into the body is not being used. This energy can be converted into fat, causing a person's overall mass to increase. In order to make sure that the energy input does not exceed the energy output, a person must ensure that they are getting enough physical excercise. Remember that energy is used in normal metabolic processes as well, concluding that exercise is not the only component that contributes to energy output.

What is the Word used when energy input is equal to energy output?
Then you can say the device has a 100% efficiency.
What is the primary type of input and output that is used in the power grid system?
energy
Define output efficiency?
efficiency eta = output / input where output is the amount of mechanical work or energy released by a process, and input is the quantity of work or energy used to run the process. Due to the principle of conservation of energy, energy efficiency within a closed system can never exceed 100%. At a loutspeaker you have electrical Voltage as input and sound pressure as output. The efficiency of the loudspeaker is really only 1 percent.

Why is modem classified as input or output?
A modem can be used for sending (output) and/or receiving (input).
Why are storage devices are output and input?
the input device get input from user.. output device display the result....
Is a buzzer an input or output device?
output cuz it got swag
Is a graphics tablet an input or output?
A graphics tablet is used to to accept user input to the computer so is classed as input device ...
CD-R input or output device?
a CD is an output device that can be used as a storage or input device
Is work input always equal to work output?
Yes the only thing a machine changes is force,distance or direction
Type of devices used as input as well as output devices?
A digital camera could be used as input as well as output devices.
