Four particles in the xy plane have the following masses and coordinates: 1 kg at (4 m, 4 m), 2 kg at (−3 m, 5 m), 3 kg at (5 m, −2 m) and 4 kg at (−2 m, −4 m). Find the total moment of inertia about:
a) the x-axis:
b) the y-axis:
b) the z-axis:
a) Add M*y^2 for the four particles
b) Add M*x^2 for the four particles
c) Add M(x^2 + y^2) for the four particles. (Or just add the first two answers)
