Homework Help: Moment of inertia of a car tire problem

  1. Apr 13, 2010 #1
    1. The problem statement, all variables and given/known data
    A side view of a car tire. Model it as having two sidewall of uniform thickness 0.635 cm and a tread wall of uniform thickness 2.50 cm and width 20.0 cm. Assume the rubber has a uniform density equal to 1.10 X 10^3 kg/(m^3). Radius from the center of the tire to the rubber is 16.5 cm. Radius from the center to the tread of the tire is 33.0 cm.

    2. Relevant equations
    None given

    3. The attempt at a solution
    p = density = m/V
    dm = p dV
    I = integral of p(r^2) dV
    surface mass density: o = pt where t = uniform thickness
