About this task
This task focuses on calculating the geometric properties of a composite I-section. Students determine the cross-sectional area, second moments of area about the principal axes, section moduli, and analyze how the section dimensions affect stiffness and strength. The task develops practical skills in composite-section analysis, evaluation of geometric properties, and preparation for problems in mechanics of materials and structural mechanics.
