If you only need the buying answer: the 180-day digital option is the cheapest route in this snapshot, with rental next. The current paperback is still lower than the sampled long-term digital option and far below the sampled used print comparator. So this is not a bad print price. It is a time-horizon decision.

What this book actually teaches
Engineering Vibration is an engineering text about oscillation, modeling, dynamics, damping, response, and problem-solving in vibrating systems. The book matters because it builds mathematical and physical intuition together, which is exactly why many students need to revisit it later rather than only read it once.
That gives the book stronger long-term value than the price table alone might suggest. Students in mechanical and civil engineering often come back to vibration concepts in later coursework, design work, and technical review.
When print is still worth buying
The honest cheapest route is the short-term digital option. But the current paperback is still below the sampled long-term digital route and far below the sampled used print comparator. That makes ownership defensible if you want a copy to keep for later engineering work rather than just for one exam window.
I would lean toward digital for a narrow one-course need. I would lean toward print for engineering readers who expect vibration concepts to reappear in later courses, design work, or review.
