4、工程机械概述
As we look around us we see a world full of “things”: machines, devices, tools;
things that we have designed, built, and used; things made of wood, metals, ceramics,

last longer, cost less, are quieter, look better, or are easier to use.

Ideally, however, every such item has been designed according to some set of
“functional requirements” as perceived by the designers — that is, it has been
designed so as to answer the question, “Exactly perform?”
In the world of engineering, the major function frequently is to support some type
of loading due to weight, inertia, pressure, etc.
