Waste of my money
I was expecting some calculators or some graphics or something for the cost. Apparently this is just a text application. I want my 2$ back!!
Nice first round
A simple reference with a bias towards SI units verses English. A better reference would provide both for material properties, shapes, etc. The subject review is a little too basic. For example, the area moment of inertia formulas for a square, circle and tube are provided, but there is no mention of the parallel axis theorem. Beam deflection formulas, moor's circle, and mc/I would be nice additions.
