Moment of inertia

Not working!

Excellent

An excellent little application. I used it through my Engineering degree and it was truly helpful and more importantly, accurate. I believe it is well worth the price as there is nothing as good as this app on the App Store. The new update seems to be a nice addition to an already great app as in makes it look more appley (if that is a word). Do not hesitate about buying this application especially if you are an engineer.
