2D Geometry Formulas 1.1 (iOS)

Five kinds of calculation methods are supported in 15 kinds of figures. This is an application for construction industry. This application carries out various calculation of a plane figure. Sectional area, height centroid, moment of inertia of section, modulus of section, and radius of gyration of area can calculate by the plane figure of 15. The result of calculation is giving an indication by an index, in order to make the range large. In addition, it is conditions that top and bottom of a rectangle (hollow) are symmetrical and that the left and right is symmetrical. Moreover, it is conditions that a square (hollow) case has the same thickness of member.
