What is the work input for a machine?
The energy that is used to make the machine work.
What is percent efficiency?
it is the amount of work that can be done. a machine can use 300,000 J of energy but it only uses 263,000 J. that is percent efficiency.
Why can't the work done by a machine be greater than the work done on the machine?
Because work is the amount of energy transferred into or out of a system, not counting energy transferred by heat conduction.
Why is the work output of a machine always less than the work input?
In a real machine, the output work is always less because input energy will be converted to heat energy and lost.
How is energy needed to make machine work?
becese it is
What is a comparison of a machine's output work toit's?
the comparison of a machine's output work toit's
The comparison between output work imput work is?
Work input is how much work you put into a machine and work output is the work done by the machine according to how much work you put into it. You will never get more work out of a machine than you put into it. The efficiency of a machine is how much useful work you got out of the machine compared to how much you put in (expressed in a percent). Efficiency = Useful Work Output ÷ Work Input
A machine that uses most of its incoming energy to do useful work is said to be?
labor saving
What is a a comparison of a machines work output with the works input that is mechanical?
Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical energy.
How does hydraulic machine work?
Hydraulic machinery uses a liquid usually oil under pressure to transmit energy, hydraulic machine use the power of fluid to work, hydraulic machine are part of our everyday life.
What is a comparison of a machine's work input and work output force?
Mechanical efficiency
What work is input for a machine?
The energy that is used to make the machine work.
What is the work input for a machine?
The energy that is used to make the machine work.
What are the uses of energy?
the uses of energy is to do work or to work the transport such as:train,planes,cars,e.t.c.......
What are the uses of a simple machine?
Doing work.
What is percent efficiency?
it is the amount of work that can be done. a machine can use 300,000 J of energy but it only uses 263,000 J. that is percent efficiency.
A machine is designed to stretch a spring uses 1550 J of energy. If the work output is 1200 J, what is the machines efficiency?
Omg wrong press
