A massless plank is placed asymmetrically over a fulcrum such that the distance from one end, call it A, to the fulcrum, is LA, the distance from the fulcrum to the other end is Lg, and LB = 3 LA. If a mass ma is placed on end A, what is the value of the mass me that must be placed at end B such that the plank is exactly balanced? Hint: balanced means there is no net torque about the fulcrum. MB MA MB = 6 MA MB = 1/6 MA MB = 3 MA MB = 1/3 MA

Correct Answer
A massless plank is placed asymmetrically over a fulcrum such that the
distance from one end, call it A, to the fulcrum, is LA, the distance from the
fulcrum to the other end is Lg, and Lg = 3 LÃ. If a mass má is placed on end
A, what is the value of the mass me that must be placed at end B such that
the plank is exactly balanced? Hint: balanced means there is no net torque
about the fulcrum.
MB = MA
MB = 6 MA
MB = 1/6 MA
MB = 3 MA
MB = 1/3 MA
