What is the difference between mechanical advantage and Efficiency?
A mechanism with a positive mechanical advantage is one in which the input force is greater than the output force. This is compensated for by the fact that the distance moved by the input is greater than the output so that in an ideal machine, the work input (Force*Distance) is the same as the work output. In real life, though, you always lose some energy - in the form of frictional heat, or sound.A negative mechanical advantage is the opposite. A small distance moved by the input is converted to a large distance moved by the output. But the force in the output is correspondingly reduced.A mechanism with a positive mechanical advantage is one in which the input force is greater than the output force.

Why is the output force always less than th input force in third clss lever?
Because the output distance is always greaterthan the input distance,and the product of (force) x (distance) is nearly the same on both ends.
Why is the output force always less than th input force in third class lever?
Because the output distance is always greaterthan the input distance,and the product of (force) x (distance) is nearly the same on both ends.
When using the wheel and axle the input force moves through a greater distance than the output force?
True
How do you find speed ratio?
Distance input --------------- = Speed Ratio Distance output The distance input divided by the distance output equals the Speed Ratio.
What is a comparison of a machine's work output and work input?
Output is always greater than input. The output is multiplied from input.
Is energy input usually greater than energy output?
The energy input is always greater than energy output.

What is the definition of output distance?
input distance- the distance the input force acts through
What is the definition of output and input work?
Work Input- The work done on a machine as the input force acts through the input distance. Work Output - The work done by a machine as the output force acts through the output distance (What the machine does to the object (dependent on the force) to increase the output distance).
If a machine has a mechanical advantage much greater than 1 how will the output force be in comparison to the input force?
The Output Force Will Most Likely Be Greater Than The Input Force. So "OUTPUT" Is Greater Than "INPUT".
When using the wheel and axle the input force moves through a greater distance than the output force?
True
How do you find speed ratio?
Distance input --------------- = Speed Ratio Distance output The distance input divided by the distance output equals the Speed Ratio.
The output force of a rake is greater than the input force?
Yes, the output force of a rake is greater than the input force.
