I was hunting for a compact, reliable companion to guide practical machine-design decisions—something that combined ready-to-use data, clear references, and real-world applicability. That’s how I found Lingaiah’s Machine Design Data Handbook, Volume 2. It wasn’t the sort of book you read straight through for theory; it’s the kind you keep at your bench or workstation, reach for when a shaft needs sizing, a bearing must be chosen, or a gear train verified.
