Part 2 explains mathematical concepts of group theory and applies them to the analysis of vibration in symmetric systems, such as rectilinear systems
, plane structural grids, and high-tension cable nets.
Arranged in largely rectilinear systems
across these opaque expanses are white markings geometric enough to remain bars and rectangles, stripes and circles, even while they coalesce into nighttime views of the modern city.
For shorter runs of less complex assemblies at slower cycle times, rotary or rectilinear systems
where robots and manual workstations take their turns in assembling, testing, and measuring components and assemblies may be selected.
