... Answer: NO! It might not be true. The expression sN is the maximum possible force of static friction. The force of static friction can be any values less than this maximum: Fstatfric sN. If the barrel is turning so slowly that the rider is just about to slip down the wall, then Fstatfric = sN. ...
