CHAPTER 2: THERMAL STRESSES AND COMPOSITE BARS


2. 1 BAR COMPOSITE
The definition of the compound bar is a bar made ​​of two or more materials with both mounted rigidly applied so that the burden can be shared and experienced the same extension @ shortening. Bars compound can be categorized into two types, series and parallel bars.



2. 2 SERIES  COMPOSITE BAR
 
Two or more bars that are mounted together by a series  (figure 2.1), can not be determined what is going on    in the bar. Therefore, an equation of deformation must be  produced, in addition to the equation the forces involved.


2. 3 PARALLEL COMPOSITE BARS
It's hard to determine what happens in a plural parallel bars   Figure 2.2). However, existing equations can be simplified.
