Still, bit by bit, archaeologists have been able to explain various mechanisms behind the building's construction. The stones themselves were mined from a quarry just south of the pyramid, and researchers believe that their journey across the desert was made easier by wetting the sand first. But that only explains how the stones got from one ...
This book covers model generation, parameter identification, balancing of mechanisms, torsional and bending vibrations, vibration isolation, and the dynamic behavior of drives and machine frames as complex systems.
