Here on earth and also on the moon two identical heavy crates (300kg) sit at rest on 2 identical level platforms with coefficients of static friction equal to (0.90). If one end of both platforms is slowly raised at the same time in both locations, will the crates eventually break free of the static friction at the same time or, because of the fact that gravity differs significantly between the two planets, will one break free sooner (i.e. at a lower angle of incline) than the other? If so, on which planet will the crate break free sooner?
