13. AN INTRODUCTION TO FOUNDATION ENGINEERING

Following erection of a structure both principal stresses in the soil will change and, in general, the total stress path will move along a line represented by NR. Immediately following erection, the effective stress path will move from point M to some point O. At the same time the pore pressure will increase from the initial value u i to a value

ELECTROMAGNETIC FORCES ACTING BETWEEN THE

If the rotor becomes eccentric, unbalanced magnetic pull (UMP) occurs. The phenomenon can be described as an imbalance of the radial and tangential forces acting upon the rotor (or stator) surface so that a net radial force is developed. The imbalance of the forces can result in vibration and noise, particularly if exacerbated by a flexible

Rotating unbalance Wikipedia

Rotating unbalance is the uneven distribution of mass around an axis of rotation. A rotating mass, or rotor, is said to be out of balance when its center of mass (inertia axis) is out of alignment with the center of rotation (geometric axis). Unbalance causes a moment which gives the rotor a wobbling movement characteristic of vibration of rotating structures.

Acoustical source separation and identification using

Acoustical signals from mechanical systems reveal the operational status of mechanical components, which can be used for machinery condition monitoring and fault diagnosis. However, it is very difficult to extract or identify the acoustical source features as the measured acoustical signals are mixed signals of all the sources. Therefore, this paper studies on the source separation and
