How does the output work compare to the input work for a machine that has an efficiency to less than 100 percent?
Then the output work is less than the input work. That description applies to every machine that has ever been built or will ever be built.
Is your power into motor equal to your power out of motor at no load?
For a motor's output power to equal its input power, the motor's efficiency must be 100%. As no machine, particularly a rotating machine, can possibly achieve 100% efficiency, there is no condition under which its output power can ever match its input power.
What type of efficiency would a simple machine have if the output work of the machine equals the input work?
Although it is impossible for any machine to have an efficiency of 100%, it would in this case be 100%. Studies have shown that when ever there is motion, there has to be a loss of energy due to friction. So any rotating machine, big or small will have losses.
Is there a machine which can repel gravity?
Nothing has ever been discovered or built on Earth that's able to repel, decrease, increase, cancel, defy, neutralize, or insulate against the effects of gravity.
Did Florida's population ever decrease in the 1900s?
no
Did Florida's population ever decrease in 1900?
no
Can the actual MA of a machine ever be greater than its IMA?
Mechanical advantage is a measure of leverage, essentially and = distance moved at input end / distance moved at output end, but the work done ( force* distance ) at each end is the same except there will be the inevitable friction losses inbetween,The efficiency of a machine is work done at output / work done at input and can never exceed 100 %
Can you make the work output of a machine greater then the work input?
No - that would violate Conservation of Energy. So far, there is no known process that violates Conservation of Energy, and it doesn't seem likely that one will ever be found.
Was there ever a time machine?
NO
When was If We've Ever Needed You created?
If We've Ever Needed You was created in 2010.
What machines can change the direction of a force?
Well, its not that hard: Some machines help people do work by changing the size of the force needed. Have you ever tried opening a door by turning the shaft instead of the handle? Not as simple. It takes less force to use the handle instead of the shaft. If a machine (doorknob attached to shaft) allows you to exert less force, you must apply that force over a greater distance. the complete and total amount of work done remains the same, whether its by machine or not. Because a machine does not change the amount of work to be done, less force must mean greater distance. So: Machine=less force BUT greater distance!
Can you ever build a time machine?
No.
