A bicycle rim has a diameter of 0.65 {\rm m} and a moment of inertia, gauged about its center, of 0.25 {\rm kg}\cdot{\rm m^2}.
What is the mass of the rim?
Express your answer to two important figures and include the appropriate units.
Consider a system consisting of three masses on the axis. Mass m1 = 1.50kg is at x = 1.40m ; mass m2 at 2.30kg is at = 2.10 m; and mass m3= 3.30kg is at = 2.60 m
