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.

Can a inclined plane have a mechanical advantage of less than 1?
The mechanical advantage of an inclined plane is equal to length divided by height (l/h). Therefore, if the length is less than than the height, the mechanical advantage would be less than one.
Why is the actual mechanical advantage of an inclined plane alwaysess than the theoretical mechanical advantage?
This is because the actual mechanical advantage is the actual calculation found after dividing the effort force by the output force. Ideal mechanical advantage is what many people would call an estimate. When estimating mechanical advantage, the numbers are always rounded. This makes actual mechanical advantage less.

Why are third class levers used if their mechanical advantage is less that one?
Mechanical advantage is not the only reason to use levers.
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.
An inclined plane reduces the effort by?
Lesser the height of inclined plane, and more the length of it, More will be the mechanical advantage of inclined plane i.e less effort would be applied.
What is true about the mechanical advantage of a machine?
it is less than the ideal mechanical advantage
What happens to the mechanical advantage of a machine if friction is reduced through the use of oil or some other means?
Wear and tear of moving parts would be reduced. Less energy would be needed to run the machine, as there would be less friction to be overcome. A well lubricated machine is more efficient than a neglected machine with unoiled parts.
If the input force is less than the input force of a simple machine the mechanical advantage is less than one?
it means the mechanical advantage is greater.
If the output force is less than the input force of a simple machine the mechanical advantage less than one?
it means the mechanical advantage is greater.
What is the formula to find mechanical advantage?
The mechanical advantage that a machine would have without friction or in another term is that you can find the IDEAL MECHANICAL ADVANTAGE (IMA) OF A MACHINE IS BY HAVING A MACHINE WITH NO FRICTION, ALSO BY MULTIPLYING YOUR EFFORT FORCE BY 2, HOWEVER BECAUSE OF FRICTION AND THE WEIGHT THE ACTUAL MA WILL BE LESS.
Can a machine be useful even if its mechanical advantage is less than 1?
yes
What is the mechanical advantage of a machine without friction?
Machinal advantage, also known as mechanical advantage, refers to the ratio of the force produced by a machine to the force applied to it. A machine can be useful even its machinal advantage is less than 1.
What is the relationship between ideal mechanical advantage and velocity ratio?
The ratio of Mechanical Advantage and Velocity Ratio is Efficiency. That is to say the ratio of M.A. and V.R. is constant.
What can be done to increase the efficiency of the machine?
Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.
Can a inclined plane have a mechanical advantage of less than 1?
The mechanical advantage of an inclined plane is equal to length divided by height (l/h). Therefore, if the length is less than than the height, the mechanical advantage would be less than one.
Is it true a simple machine is one that always gives a mechanical advantage of 2?
No. A simple machine such as a lever could quite easily give a mechanical advantage of 10, 100 or more, or could even be less than 1.
How does actual mechanical advantage compare with ideal mechanical advantage?
The actual mechanical advantage is usually less, due to losses.
