Question

a hammer has an input distance of 3 cm and an output distance of 9 cm. what is its ideal mechanical advantage?
a 1/2
b 1/6
c 1/3
d 1/9

Explanation:

Step1: Recall the formula for ideal mechanical advantage (IMA)

IMA = \(\frac{\text{Input distance}}{\text{Output distance}}\)

Step2: Substitute the given values

Input distance = \(3\) cm, Output distance = \(9\) cm.
IMA = \(\frac{3}{9}\)

Step3: Simplify the fraction

\(\frac{3}{9}=\frac{1}{3}\)

Answer:

C. \(1/3\)
