A crowbar of length $2.5 m$ is pivoted at a point $25 c m$ from its tip. Calculate mechanical advantage of crowbar.

Open in App

Solution

Given:
Load arm= $25 c m = 0.25 m$
Effort arm $= 2.5 - 0.25 = 2.25 m$

To calculate Mechanical Advantage,
Formula used: $M A = \frac{L o a d a r m}{E f f o r t a r m }$
$M A = \frac{2.25}{0.25} = 9$

Answer:
Hence, the mechanical advantage is $9$
