Question

In a class two lever,the loadarm is 80cm and the distance between the load and te effort is 120cm, Find the mechanical Advantage
Correct Answer= Brainlisted

Answer 1

Given that,

FA = Effort of arm = 80cm

Load of arm = 120cm

Machanical advantage = Effort arm / Load arm

• 80cm/120cm
• 2/3 cm

Therefore, the machanical advantage is 2/3cm.

Hope this helps you.
