A machine with an ima (ideal mechanical advantage) less than 1 is called a disadvantage machine, meaning it doesn't amplify input force. An example is a system where the output force is less than the input force due to friction or other factors, such as a pulley system with multiple moving parts.
A simple machine with an IMA (ideal mechanical advantage) less than 1 is a machine where the output force is greater than the input force. A common example is a pulley system where the IMA is equal to the number of supporting ropes.
Efficiency is equal to the ratio of work input to work output; for an ideal machine this ratio is equal to 1 or 100%. For a real machine this ratio is always less than 1 because some of the work input is used to overcome mechanical friction within the machine which does not contribute to the work output of the machine.
well the advantage of that is pie, not math pie but pie that you eat
Mechanical advantage is less than 1 when the output force is less than the input force. This means that the machine is not amplifying the force applied and is actually requiring more effort to move the object. Mechanical advantage less than 1 is often seen in situations where the machine is designed to increase distance or speed at the expense of force.
(AMA / IMA)100 Where AMA represents the actual mechanical advantage and IMA represents the Ideal Mechanical advantage. AMA = Fr/Fe where Fr equals the force of the resistance from the fulcrum, and Fe equals the force of the effort. IMA = De/Dr where De equals the Distance of the effort from the fulcrum and Dr equals the distance of the resistance from the fulcrum

The IMA of a machine is greater than 1 whenever the output force is greater than the input force.
It tells me that the machine is imaginary and does not exist.
yes

Mainly because that's the only kind you can ever get. If you hold out until you find a machine with a mechanical advantage of not less than 1, you'll never get the job done. Or even started.

Yes some energy is lost in the form of heat and so the efficiency of the machine is always less than 1 ie 100%
