Mechanical Advantage

Mechanical Advantage -The number of times the force exerted on a machine is multiplied by the machine. (Output Force / Input Force)

Mechanical Advantage (MA) Example

If a simple machine had a MA of 2, it would take just over 50 newtons of effort to lift a 100-newton load.

Work

The application of Force over a distance. Formula is W = Fd (work = force * distance)

How do we (be able to) calculate work?

multiply the force by the distance or W = Fd

Ideal Mechanical Advantage

The mechanical advantage that a machine would have without friction. (Length of Incline / Height of Incline) ex. Doubling the length of the ramp doubles the mechanical advantage.

Actual Mechanical Advantage

The mechanical advantage that a machine provides in a real situation (Output Force / Input Force) It is the same as the mechanical advantage!
