Solution

Step 1. Given data:
Load arm = $2$ m
Mechanical advantage = $3$
Step 2. Calculate the effort:
$M e c h a n i c a l a d v a n t a g e = \frac{E f f o r t a r m}{l o a d a r m} E f f o r t a r m = l o a d a r m X M e c h a n i c a l a d v a n t a g e E f f o r t a r m = 2 X 3 E f f o r t a r m = 6 m$
Hence, ff the load arm is 2 m and the effort arm is 6 m, then the MA is 3.
