  • Moment of inertia of triangle about centroidal axis - Physics Forums
    The situation is this: I know the moment of inertia with respect to the x-axis and with respect to the centroidal x-axis because its in the table Now based on symmetry you can apply the definition of the moment of inertia to calculate the moment of inertia about the y-axis which equals the cendroidal y axis But I don't know how to do that
  • Moment of Inertia in Equilateral Triangle - Physics Forums
    The problem is to find the moment of inertia for a solid equilateral triangle about an axis at the triangle's vertex which is perpendicular to the plane of the triangle Mass is given as M I was wanting to treat it like 3 point masses at each vertex with 1 3 mass Then I could use the sum definition of moment of inertia instead of the integral
  • Area moment of inertia of inverted triangle? - Physics Forums
    So the (depth of the) centroid is NOT the same for an inverted triangle Gate is inverted triangle => hc=6+(1 3)3=6+1=7 Gate is NOT inverted triangle => hc=6+(2 3)3=6+2=8 So why doesn't the second moment depend on the "weighted" position of the triangle I understand that I may be mixing apples and oranges, it just doesn't fit in my head
  • Calculating Moment of Inertia for Sierpinski Triangle - Tips and Tricks
    Let I be the moment of inertia around the center of the fractal Consider now just one section of the fractal One section has one third of the mass and is scaled down by a factor of two, so the moment of inertia of one section about its center is (I 12); multiply by one third because of the mass change, and by one half squared because of the scalin
