Serious neck injuries can occur when a football player is struck in the face guard of his helmet in the manner shown, giving rise to a guillotine mechanism. Determine the moment of the knee force P=50 lb about point A. What would be the magnitude of the neck force F (lb) so that it gives the counterbalancing moment about A?
