Want this question answered?
Entropy. There are always losses - usually by friction.
There are always energy losses within the machine due to inertia, friction, etc.
Machine without any friction is an ideal machine so an ideal machine cannot have friction.
TNSTAFL There's no such thing as a free lunch. There are ALWAYS losses in any machine (friction being the most common) There is a joke exception - the electric heater ... since the losses are the desired result.
A. By decreasin the work inut to the machine without increasing output B. By reducing losses due to friction C. By increasing the ork ouput of the machine wihout increasing input D. All of the above D. ALL OF THE ABOVE
yes
It maximizes it, by reducing the internal losses to friction.

By reducin friction between the machine parts and also by avoiding any sorts of power losses.

Reduce losses from friction so forth in transmission of power. Ensure fuel utilized to the fullest.
No. Work out is always less than work in due to friction and other losses..

An efficiency factor of 1 (or 100% efficiency) is not possible due to losses that cannot be reduced to zero. These losses take the form of friction, heat loss etc.

Friction makes a machine less efficient by wasting energy.
