Explain principle of lever with mechanical advantage
Asked by alishabhosale25.6spicertl | 21 Jul, 2020, 04:49: PM
Expert Answer
According to the principleof lever,
Load × Load arm = Effort × Effort arm
Thus,
L × BF = E × AF
Thus, mechanical advantage is the ratio of length of its effort arm to the length of its load arm. This is known as the law of levers.
From the above equation, we get
(i)If effort arm = load arm, M.A. = 1
(ii)If effort arm < load arm, M.A. < 1
(iii)If effort arm > load arm, M.A. > 1
