For a certain bridge project that is being evaluated, it was decided, at first, to use an I-section beam, as shown in the following image. Considering the given dimensions and the orientation of the Cartesian axes, we ask: what is the value of the static moment, or first order moment, of the cross section, in cm³? HASSE, D. Geometric characteristics of plane figures. São José dos Campos: Workbook on the resistance of materials, 2010. Options: a) The static moment of the section is 555.85 cm³. B) The static moment of the section is 385.95 cm³. c) The static moment of the section is 456.90 cm³. d) The static moment of the section is 512.25 cm³. e) The static moment of the section is 488.75 cm³.
