Question

A fulcrum moving a resistance of 200 g has a distance to the fulcrum of 20 cm, the effort mass of 50 g has a distance to the fulcrum of 80 cm. The resistance moves 10 cm, the effort moves 40 cm. Calculate the AMA.

Answer 1

AMA=4

IMA=4

100% efficient

Answer 2

AMA value is 4.

Step-by-step explanation:

AMA is known as Actual mechanical advantage

It can be calculated by the following formula

MA = FB / FA

MA = mechanical advantage,

FB = force of the object

FA = effort to overcome the force of the object.

Given: FB=200

FA=50

MA=200/50

MA=4

Actual mechanical advantage takes into account energy loss due to deflection, friction, and wear.
