Homework Help: How to specify the normal force for this example

    1. The problem statement

    Hi, I just have a quick question on how to find the normal force in this picture on mass 2, http://postimg.org/image/w9sr29ab3/ , the half circle. Its a double pendulum with no friction. Can I assume that the normal force is in that position all the time as the half circle goes back and forth.

    thx for any help
