Abstract: With the rise of new technological revolution, mechanics calls for revitalization to accommodate the characteristics of the new era, and the undergraduate phase of higher education is the first to be affected. Based on the guidelines of mechanics development and teaching practices in the Department of Mechanics Engineering of Zhejiang University, a new undergraduate curriculum is proposed for the mechanics major, in which the basic courses are taken as the root, the core professional courses as the trunk and the multidisciplinary courses as the leaves to form the tree of mechanics. We hope that this new curriculum, or "Mechanics 3.0" for abbreviation, may provide a guidance for mechanics higher educators.
