1. The problem statement, all variables and given/known data A pilot flies a loop-the-loop maneuver at constant speed. Two forces act on the pilot- the force due to gravity and the normal force of the seat pressing on him. Rank the largest to smallest normal forces on the pilot when [a. he is at the bottom of the loop right side up] [b. he is ascending vertically into the loop] or [c. he is upside down at the top of the loop] 2. Relevant equations Doesn't look like there's any math involved. 3. The attempt at a solution I don't really understand the concept, so an explanation would be awesome.
