What to Focus On

  • A machine helps overcome load by applying effort.
  • Input work is done by the effort.
  • Output work is done by the machine on the load.

  • Mechanical advantage compares load and effort.
  • Velocity ratio compares motion of effort and load.
  • Efficiency compares output work and input work.

  • Energy is supplied at the effort point.
  • Useful work is obtained at the load point.
  • Ideal machines have no energy loss.

Common Mistakes to Avoid

A machine always acts as a force multiplier.

Mechanical advantage and velocity ratio are the same thing.

Velocity ratio changes whenever friction changes.

Memory Tips

Machine as a force multiplier, speed gain, or direction changer

Velocity ratio definition

Efficiency as output work over input work

Relationship among efficiency, mechanical advantage, and velocity ratio
