Three men pull on ropes attached to the top of a heavy object which is level with the ground. Man A is 6 ft. tall, stands 6 ft. away, 45 degrees NE from the center of the object and exerts a force of 72 lbs. Man B is 5 ft. 6 in. tall, 6 ft. away, 60 degrees NW and pulls with a force of 60 lbs. Man C is 5 ft. tall, also stands 6 ft. away, 30 degrees SE and pulls with a force of 80 lbs. Assuming the ropes are attached to their shoulders which are 2/3 of their height from the ground, what is the magnitude of the horizontal resultant (in lbs) of these forces on the object?
