A rectangular section polypropylene beam has a length, L of 200 mm and a width of 12 mm. It is subjected to a load, W, of ISO N uniformly distributed over its length, L, and it is simply supported at each end. If the maximum deflection of the beam is not to exceed 6 mm after a period of I year estimate a suitable depth for the beam. The central deflection of the beam is given by... 

Consider the general class of laminated rectangular plates that are simply supported along edges x = 0, x = a, y = 0, and y = b and subjected to a distributed transverse load, p(x,y). In Figure 5-8. The transverse load can be expanded in a double Fourier sine series ...

While the smooth substrate considered in the preceding section is sufficiently reahstic for many applications, the crystallographic structure of the substrate needs to be taken into account for more realistic models. The essential complications due to lack of transverse symmetry can be dehneated by the following two-dimensional structured-wall model an ideal gas confined in a periodic square-well potential field (see Fig. 3). The two-dimensional lamella remains rectangular with variable dimensions Sy. and Sy and is therefore not subject to shear stresses. The boundaries of the lamella coinciding with the x and y axes are anchored. From Eqs. (2) and (10) one has... 

Double torsion test specimens take the form of rectangular plates with a sharp groove cut down the centre to eliminate crack shape corrections. An initiating notch is cut into one end of each specimen (Hill Wilson, 1988) and the specimen is then tested on two parallel rollers. A load is applied at a constant rate across the slot by two small balls. In essence the test piece is subjected to a four-point bend test and the crack is propagated along the groove. The crack front is found to be curved. 

Of much greater relevance in micro reactors are rectangular channels, which were the subject of a study by Cheng et al. [110], among others. They solved the Navier-Stokes equation for channel cross-sections with an aspect ratio between 0.5 and 5 and Dean numbers between 5 and 715 using a finite-difference method. The vortex patterns obtained as a result of their computations are depicted in Figure 2.20 for two different Dean numbers.

Commercial cells are generally rectangular (prismatic) in shape and the case is usually plastic, with a rugged construction to withstand the mechanical stress to which this system is often subjected. The cells are sealed, but... 

The aseptically-processed concentrates retained sterility throughout the course of the study and were stored at 7.2° and 23.9°C. The samples in 6-oz. foil-lined composite cans and those cold filled into the 200-ml rectangular packages were stored only at -17.8°C because, they were not aseptically packed and were subject to microbial spoilage.
