How can you increase the mechanical advantage of a lever?

Open in App

Solution

Mechanical advantage of the lever is equal to the ratio of effort arm to the load arm.

𝑀𝑒𝑐ℎ𝑎𝑛𝑖𝑐𝑎𝑙 𝑎𝑑𝑣𝑎𝑛𝑡𝑎𝑔𝑒 𝑜𝑓 𝑙𝑒𝑣𝑒𝑟
$= \frac{L o a d (L)}{E f f o r t (E)}$ $= \frac{E f f o r t a r m}{L o a d a r m}$

It can be increased by increasing effort arm or by decreasing load arm.
