nicolas Posted August 25, 2011 Share Posted August 25, 2011 Hi, I am looking into the various sectional information that can be gleaned from a closed profile using a combination of region, ucs at profile centroid and massprop. I can easily get Ix and Yx Inertia. However, I have been asked to find Ix/V. Can anybody help me with finding the Ix/V given that I have the centroid, Ix and Iy? In my research, I came across a lisp called modulus.lsp that calculate section modulus but I have serious doubt about the unit used namely cm3? Does anybody knows this lisp or are there any other lisps that can be used to determine Ix/V? Regards, Nicolas. Quote Link to comment Share on other sites More sharing options...
SLW210 Posted August 25, 2011 Share Posted August 25, 2011 Moment of Inertia should be in the unit of cm4. Section Modulus is in unit of cm3. The formula for Moment of Inertia is based on shape. You should probably check out some engineering forums to help you along. If I get time I will look into it. Quote Link to comment Share on other sites More sharing options...
