Principle of Moments: The moment caused by the weight must equal the moment caused by the applied force.
Moment = Force x Distance
Weight Moment = Applied Force Moment
300 N x 0.8 m = F x 4.5 m
240 N m = F x 4.5 m
F = 240 N m / 4.5 m
F = 53.33 N
Answer: The magnitude of the force applied is 53.33 N.
