I occasionally teach this course, Mechanics 1: Statics, at the University of California, San Diego, as part of the undergraduate curriculum in the Structural Engineering Department. This course serves as the first exposure to mechanics for structural engineering students. I consider it a basic, yet crucial and foundational, course for civil engineers. At present, the notes do not include content on centroids and moments of inertia. I’ve broken down the lectures in this course into 26 manageable chapters.

Please note that these lecture notes are a work in progress. You may (and likely will) encounter typos or minor (or major) errors. I do my best to update and correct them as I discover them—usually when I teach. I hope you find these notes useful.
