which factor increases as the efficiency of a machine increases

Because all machines lose input work to friction, one way to improve the efficiency of a machine is by reducing friction. Oil is used to reduce friction between the moving parts of car engines. The use of oil makes engines more efficient. Another machine that loses input work is a bicycle.

The factor which increases as the efficiency of a machine increases is: work output.

Efficiency can be defined as a ratio of work (energy) output to work (energy) input.

Mathematically, the efficiency of a machine is given by the formula:

[tex]Efficiency = \frac{W_O}{W_I} \times 100[/tex]

Where:

Wo is the work output.

Wi is the work input.

Work can be defined as the amount of energy required to move an object from one point to another.

Hence, the work done by a machine is the product of the perpendicular force acting on the machine and the distance it covers or travels.

Ideally, the work output of a machine is highly dependent on its efficiency and as such, it is a factor which increases as the efficiency of a machine increases
