The following will be discussed in this chapter: Deformation of a beam under transverse loading, equation of the elastic curve, direct determination of the elastic curve from the load di, statically indeterminate beams, application of superposition to statically indeterminate, moment-area theorems,...
Concrete has been in use as a primary building material since Roman times. As it is
strong in compression but weak in tension, it was used in arches, vaults and walls
where it is stressed principally in compression.
In the mid-nineteenth century, it was discovered that iron and later steel bars could
be embedded in the concrete, effectively giving it tensile strength. This allowed it to be
used in beams and slabs, where it worked in bending. Buildings, bridges, retaining walls
and many other structures were made in this reinforced concrete.
(BQ) The objective of ebook Structural analysis is to develop an understanding of the basic principles of structural analysis. Emphasizing the intuitive classical ap proach, structural analysis covers the analysis of statically determinate and indeterminate beams, trusses, and rigid frames. It also presents an introduction to the matrix analysis of structures.
Flow cytometry is a technology that simultaneously measures and analyses multiple
physical characteristics of single particles, usually cells, as they flow in a fluid stream
through a beam of light. The properties measured include a particle’s relative size
(represented by forward angle light scatter), relative granularity or internal complexity
(represented by right-angle scatter), and relative fluorescence intensity.
