How would you make the work output of a machine greater?

I can think of two strategies:

1).  Reduce/remove as much friction as possible from the
internal guts of the machine.  Reduce the areas where two
surfaces contact each other, and use oil or grease to lubricate
the areas that can't be reduced.

2).  Make the work INput greater.

No because a circle or pie graph usually shows percentages you'd need a line graph

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then
