Mechanical Advantage

Question 1

Simple machines

Answer 1

Inclined plane, wedge, wheel and axle, lever, pulls, and screw

Question 2

Mechanical advantage

Answer 2

Ratio of magnitudes of the force exerted on an object by a simple machine (Fout) to the force actually applied on the simple machine (Fin)
MA=Fout/Fin
Distance through which the smaller force must be applied in order to do the work must be increased

Question 3

Efficiency

Answer 3

Wout/Win=[load•load distance]/[effort•effort distance]

Question 4

Load

Answer 4

The output force of a simple machine

Question 5

effort

Answer 5

The input force or a simple machine
