Mechanical Aptitude Levers
How to Solve Mechanical Aptitude Levers Problem.
Theory:- You have to balance the Torque of both side about Hindge.
I.e Torque of Anticlockwise/ = Torque Required in Clockwise/Anticlockwise to balance the weight
Apply the formula
w x d1 = f x d2 can be rearranged to f = (w x d1)/d2
This type of problem can be solved like this:
f = (w1 x d1) + (w1a x d1a)/d2
1) How much weight is required to balance the lever?
A.15kg B.10kg C.7.5kg D.5kg
