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!
