Problem 8.1 - Centroid

Problem Statement

For the composite cross-section shown, determine the centroid location, measured from the base. Assume dimensions b1 = 20 mm, b2 = 130 mm, h1 = 6 mm, h2 = 130 mm, and t = 4 mm.

A composite cross section has a base of height h1 and a hollow square of height h2. The base is of length 2b1+b2 and the hollow square has a thickness of 4 mm. [Problem adapted from © Chris Galitz CC BY NC-SA 4.0]
