What simple machine has an IMA less than 1?
simple machine.
What is the formula for lever?
(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 efficiency of a real machine?
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.
Describe why a high-efficiency machine is more desirable than a low-efficiency machine?
Efficiency is the ratio of the energy converted into useful work by the machine to the energy supplied to the machine. Certainly it will not be possible to convert all the energy supplied into useful work because of wastage of energy due to so many reasons. So efficiency will be always less than 1. As the efficiency becomes more the loss would become less. Hence it is desirable.
If the output force is greater than the input force of a simple machine Is the mechanical advantage is less than one?
No, the mechanical advantage is greater than 1. If you input a force of 1 unit you get out a force of 1+ units. However keep in mind that if this were a PERFECT machine the amount of WORK INPUT is EQUAL to the the amount of WORK OUTPUT. Since perfection is not possible, and there are frictional losses this is not possible. Otherwise you could have a perpetual motion machine, which is not yet possible.
What simple machine has an IMA less than 1?
simple machine.
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.

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.
The efficiency of a real machine?
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.
Can a machine be useful even if its mechanical advantage is less than 1?
yes
Why would you want to use a machine with a mechanical advantage less than 1?
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.
In a machine work output is less than work input because some energy is converted into thermal energy.?
Yes some energy is lost in the form of heat and so the efficiency of the machine is always less than 1 ie 100%
In a machine work output is less than work input because some energy is converted in thermal energy?
Yes some energy is lost in the form of heat and so the efficiency of the machine is always less than 1 ie 100%
