Explanation:
The mechanical advantage is a factor that measures how input force increases using a machine.
A lever is a simple machine with the fulcrum at the center.
To calculate the mechanical advantage M.A of levers we use the expression below;
M. A = =
= input force
= output force
a is the distance of the input force from the fulcrum
b is the distance of the output force from the fulcrum
Given
a = 36cm
b = 6cm
M.A = = 6
