Conceptional doubts in making FBDs

  1. Aug 24, 2014 #1
    1. The problem statement, all variables and given/known data

    I just have some conceptional doubts and it would really be appreciated if some one would answer!
    Q1. What is net contact force?
    Q2. Does it have friction as one of its components?
    Q3. Is it any way similar to normal force?

    2. Relevant equations



    3. The attempt at a solution
    I did try to read through Halliday Resnick Jearl Walker Physics textbook, but I wasn't satisfied.

    When speaking about contact force in Mechanics, it usually includes both the normal force and friction.
    Do you have any special problem?
