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.
Can the work output of a machine ever be greater than the work output?
No, the work output of a machine cannot be greater than the work input. This violates the principle of conservation of energy, which states that energy cannot be created or destroyed, only transferred or converted. Any machine that claims to produce more work output than its input is operating outside the laws of physics.
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.
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
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
Why is the ama of a machine always less than the ima of a machine?
The actual mechanical advantage (AMA) of a machine is always less than the ideal mechanical advantage (IMA) due to factors such as friction, inefficiencies in the machine's design, and other losses of energy. As a result, the actual output force of a machine is typically less than the input force required to operate it, leading to a lower actual mechanical advantage compared to the ideal mechanical advantage.
The mechanical advantage of a machine is always greater than 1?
False. The mechanical advantage of a machine can be greater than, equal to, or less than 1, depending on the type of machine and how it is designed.
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.
What happens when the output force is greater than the input force on a simple machine?
When the output force is greater than the input force on a simple machine, the machine provides a mechanical advantage, making it easier to perform work. This allows the machine to lift or move heavier loads than would be possible with just the input force alone.
What happens when actual sales are greater than forecasted sales?
inventory will decline.
