What is the formula for lever?

Answer 1

(AMA / IMA)100 Where AMA represents the actual mechanical advantage and IMA represents the Ideal Mechanical advantage.

AMA = Fr/Fe where Fr equals the force of the resistance from the fulcrum, and Fe

equals the force of the effort.

IMA = De/Dr where De equals the Distance of the effort from the fulcrum and Dr

equals the distance of the resistance from the fulcrum

Answer 2

The ideal mechanical advantage of a lever is always

(length of effort arm) divided by (length of resistance arm).

-- First-Class Levers can have any IMA, less than 1 or more than 1.

-- Second-Class Levers always have an IMA greater than 1 (<1)

-- Third-Class Levers always have an IMA less than 1 (>1)

Answer 3

length of effort arm / length of resistance arm

Answer 4

the formula for a lever is Mechanical Advantage=load/effort

Answer 5

Mechanical advantage=load(l):effort(E)

Answer 6
