Question
A pair of scissors has its blades 15 cm long, while its handles are 7.5 cm long. What is its mechanical advantage?
Numerical
Solution
Length of blades = 15 cm = Load arm
Length of handles = 7.5 cm = Effort arm
Mechanical advantage M.A of scissors = `"Effort arm"/"Load arm"`
= `7.5/15`
= `1/2`
= 0.5
