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 %

When is the mechanical advantage greater than one?
The IMA of a machine is greater than 1 whenever the output force is greater than the input force.
Is zero Greater than 8?
no 0 is NEVER greater than 8! EVER
Is 42.53 greater than or less than 42.35?
42.53 is greater than 42.35 because you look at the number to the right of the decimal, and which ever is greater, is the answer
What does a mechanical advantages less than 1 equal to 1and greater than 1 tell you about the machine?
It tells me that the machine is imaginary and does not exist.
Can a simple machine efficiency ever be greater than 100 percent?
No, due to the fact machines loose energy due to heat/thermal energy. you will always loose some amount of energy.
When is the mechanical advantage greater than one?
The IMA of a machine is greater than 1 whenever the output force is greater than the input force.
Why can't the force that comes out of a machine be greater than the force that goes into a machine?
It sure can. A machine as simple as a lever can produce an output force that is greater than the input force. Perhaps you are confusing "force" with "energy"?
Is actual yield greater or less than theoretical yield?
The actual yield is less than the theoretical yield.
Is zero Greater than 8?
no 0 is NEVER greater than 8! EVER
Estimate 199 over198 plus 35 over 17 indicating if the actual answer is greater than or less the estimate?
199 over 198 estimate = 1 actual answer would be greater than 1 35 over 17 estimate = 1 actual answer would be greater than 1
Can gravity ever be greater than friction?
my dear gravity is forever greater than friction and strong atomic force is greater than gravity
Is 42.53 greater than or less than 42.35?
42.53 is greater than 42.35 because you look at the number to the right of the decimal, and which ever is greater, is the answer
What does a mechanical advantages less than 1 equal to 1and greater than 1 tell you about the machine?
It tells me that the machine is imaginary and does not exist.
Can you make work output of a machine greater then the work input?
No. And you cannot make it greater THAN the input, either.
Is it true or false that in some machines the output force is greater than the input force?
Output force CAN'T be absolutely greater than input force because energy is lost due to friction. However, the "mechanical advantage" of a simple machine can be greater than one because the machine applies the force over a different distance.
What happens when actual sales are greater than forecasted sales?
inventory will decline.
How do you do greater than and less than with fractions?
You find the common denominator for both fractions and which ever has the highest numerator is greater.
