Homework Help: Moment of inertia of triangle about tip formula

  1. May 22, 2009 #1
    1. The problem statement, all variables and given/known data
    Calculate the moment of inertia of a 4 blade propeller

    2. Relevant equations

    3. The attempt at a solution

    I am assuming the propeller blades to be triangles and need a formula for the mass moment of inertia about the tip of each triangular blade. Google hasn't helped thus far. Integration isn't necessary.

    Case closed. I sucked it up and did the integral.
