Angle Bending Curve

The angle bending in H2O occurs without breaking any bonds, and the electron correlation energy is therefore relatively constant over the whole curve. The HF, MP2 and MP4 bending potentials are shown in Rgure 11.13, where the reference curve is taken from a parametric fit to a large number of spectroscopic data.

Ducts are used to transport the exhaust air and its contaminants to the collection area. An important feature of duct design is reduction of resistance to air flow from friction within the wall, aggravated by unnecessary curves and bends (particularly right-angled bends), as well as junctions with other ducts at sharp angles, collections of dust, and changes in duct diameter. 

Wind tunnel is directly linked with the shaft together and tries to reduce the number of turning, which angle is less than sixty. All the connection comers should be smooth, especially the inside comer, which should be put into a double curves, we should use a sleek obtuse angle bend instead of an elbow bend. 

In compression, a single large flaw is not fatal (as it is tension). As explained in Chapter 17, cracks at an angle to the compression axis propagate in a stable way (requiring a progressive increase in load to make them propagate further). And they bend so that they run parallel to the compression axis (Fig. 20.7). The stress-strain curve therefore rises (Fig. 20.8), and finally reaches a maximum when the density of...
