Forces on stack of books

  1. Sep 25, 2004 #1
    :confused: :confused: :confused: :confused: :confused: :confused:
    TWO BOOKS ARE STACKED ON TOP OF EACH OTHER ON A LEVEL TABLE. THE MASS OF THE UPPER BOOK IS GREATER THAN THE MASS OF THE LOWER BOOK. WHAT FORCES ARE EXERTED ON THE UPPER BOOK AND LOWER BOOK? DO ANY OF THESE FORCES HAVE EQUAL MAGNITUDE?

    HELP IM A FIRST TIME PHYSICS STUDENT THIS IS SO HARD!

    Please in the future 1. Do not post threads that have excessive random character usage and 2. Please don't make posts in all capitals.

    Since all the objects are in static equilibrium (not moving), the sum of the forces on all of the objects in question are equal to zero. For the top book this means that the force of gravity pushing down on it is being negated by the normal force pushing upward from the book beneath it. I think you can probably extend these ideas to the book on the bottom
