First, the title and author. The user mentioned "Mehmet H. Omurtag Statik ve Mukavemet PDF [UPDATED]". So the Turkish titles correspond to Statics and Strength of Materials. The author is Mehmet H. Omurtag. I wonder if there's an English version or if this is purely a Turkish-authored/textbook. The [UPDATED] part might mean there's a revised edition or some additional material.
