SUMMARY
The discussion focuses on calculating the magnitude of the downward force exerted on the fulcrum of a teeter-totter with an 80-kg man and a 20-kg boy. Using the principles of static equilibrium, the weight of the boy is determined to be 20 kg by applying the momentum equation ΣM=0. Subsequently, the total downward force (Ff) on the fulcrum is calculated using the force equation ΣF=0, resulting in a total force of 981 Newtons.
