Chapter 10, Problem 28P

For a beam with the cross-section shown, calculate the moment of inertia about the z axis. Assume the following dimensions: by-83mm h₂ = 15 mm by 9 mm b₂-72 mm by-35 mm h-24 mm The centroid of the section is located 65 mm above the bottom surface of the beam. M₂ H Answer: mm by

Determine the moment of inertia and radius of gyration of the beam's cross-sectional area about the centroidal x and y axes. 30 mm 200 mm 30 mm 300 mm 30 mm 30 mm

Determine the moment of inertia of the beams cross sectional area with respect to the x acis passing through the centroid C of the cross section. Let y = 104.3 mm
