Moments of Inertia

If you need a beam's moments of inertia, cross sectional area, centroid, or radius of gyration, you need this app. This app was created to assist you in these calculations and to ensure that your beam section calculations are fast and accurate. Simply select from the available geometries, enter in the required dimensions and the answers will be generated complete with the formulae. You can also easily print or email a PDF of your results along with a schematic of the beam's cross section.

Moments of Inertia Features:

• Designed for use on all sizes of the iPhone, iPod Touch, and iPad
• Extremely flexible unit system that has the ability to perform unit conversions on the output
• Save multiple cases of each solution for later reference
• Printing Capability
• Ability to email a PDF of the Cross Section Schematic, Inputs, Equations, and Results

The properties calculated include are:

• Moments of Inertia about the x & y axes
• Polar Moment of Inertia
• Radius of Gyration
• Centroids
• Area
• Section Modulus

Moments of Inertia calculates the properties and displays the equations for many sections including: • Rectangles • Hollow Rectangles • Circles • Hollow Circles • Semicircles • Quarter Circles • Ellipses • Triangles • I Beams • Tee Sections • Channel Sections • Unequal-Legged Angle
