Solution

Step 1: Given data
Load lifted $= 200 N$
Effort applied $= 50 N$
Step 2: Formula used
: $M A (m e c h a n i c a l a d v a n t a g e) = \frac{L o a d}{E f f o r t}$
Step 3: Substituting the value of Load and Effort we get
$M A = \frac{200 N}{50 N} M A = 4$
Hence the mechanical advantage of a given simple machine is equal to $4 .$
