Vibration Analysis for Machinery Health Diagnosis

a speed which excites resonance in the machine. Many times a forcing function (such as from a rotating shaft) excites a resonance frequency in another part of the same or nearby machine. This resonance frequency may be identified by an impact test, typically when the machine is ff; the machine structure may be "rung" like a bell.

Chapter 6: Analysis of Structures - Purdue University

Generalizing the structure of planar trusses to 3D results in space trusses. The most elementary 3D space truss structure is the tetrahedron. The members are connected with ball-and -socket joints. Simple space trusses can be obtained by adding 3 elements at a time to 3 existing joints and joining all the new members at a point.
