When a beam is asymmetrical, the maximum and minimum moments of inertia are not around the X-Y axes. Formulas for these properties originally contain integrals but simplify to algebraic expressions when they’re referenced to the centroid. when type STL nothing happens.I don't have any experience with autolisp routines, so I was wondering if you can help me out with the program.Thank you in advance.The parallel axis theorem is: I p = I + Ad 2 When the Lisp program calculates these fundamental sectional properties, they are used to find the product of inertia, polar moment of inertia, and radius of gyration.
