Homework Help: Helicopter Forces

  1. Oct 4, 2006 #1
    In a free-body diagram of a helicopter carrying a suspended object, what force exists to keep the helicopter aloft? Is there a normal force from the rotors? Any help would be appreciated.

    Hint: What is the purpose of the rotors? What force to they provide?

    while the rotors rotate, they apply a force on the air. What does an object do to you when you apply a force on it?
