Lever Systems and the Mechanical Advantage of Levers

Question 1

First class leaver

Answer 1

Axis is located in the center of the leaver with the resistance and force on either end

		§ Header in soccer

Question 2

Second class leaver

Answer 2

Resistance is located in the center of the leaver with the axis and force on either end

		§ Push up position

Question 3

Third class leaver

Answer 3

Force is located in the center of the leaver with the resistance and axis on either end

> Bicep curl

                      > Kicking a ball

Question 4

Mechanical advantage

Answer 4

○ Force arm / resistance arm = mechanical advantage

		>  If the resistance arm is extended the MA= ^ acceleration & decrease force
                    > If the force are is longer then the MA=^ force & decreased acceleration
