A current problem in the U.S. Air Force is the neck/shoulder fatigue experienced by pilots. To be able to fly missions at night, the pilots wear night vision goggles, which are attached to the front of the helmet. Unfortunately, these are heavy, causing a large downward torque of the head, which must be counteracted by the neck muscles, which then fatigue. To alleviate this problem, many pilots have started attaching random lead weights to the back of the helmet. Find the appropriate weight that would best balance the head and minimize neck fatigue – You must show your free body diagram. Assumptions: a) center of gravity of goggles is 20 cm in front of neck pivot point, b) load of goggles1.0 kg mass, c) center of gravity of lead weight is 10 cm behind neck pivot point, d) load of bare helmet 3 kg mass, e) center of gravity of helmet is 2 cm in front of neck pivot, f) load of head 4.0 kg mass, and g) center of gravity of head is right at neck pivot point.
