Round Corners

Total thermal expansion between anchor points is in inches. 

Loops having round comers can be solved as follows  

If the square comer solution causes reactions and stresses which exceed acceptable limits 

If the radius of the bend is more than 1.5 pipe diameters 

H = height of the loop which must be equal on both sides.

A considerable reduction in stress concentration could be achieved by using a cross-bore which is eUiptical in cross-section, provided the major axis of the eUipse is normal to the axis of the main cylinder. A more practical method of achieving the same effect is to have an offset radial hole whose axis is parallel to a radius but not coincident with it (97,98). Whenever possible the sharp edges at the intersection of the main bore with the cross bore are removed and smooth rounded corners produced so as to reduce the stress raising effects. 

Baffles and stiffeners inside tanks should be arranged to allow free drainage to the bottom of the vessel. The bottom should slope downwards and have rounded corners. Any drain valves or plugs should fit flush with the bottom (Fig. 9.16). 

Basically, in the vicinity of a sharp comer all fringes converge toward the apex. Having a high density of lines at this point indicates the presence of high stress level. At a rounded corner there will be considerably less concentration. Besides the molding problems, sharp corners often cause premature failure because of the stress concentration. To avoid these problems, inside comer radii should be equal to one-half the nominal wall... 

The inside surface is smooth with rounded corners and no internal fixtures such as baffles. 

Great care is taken that we design blow molds to avoid thin or weak regions that could result in premature failure. Molds are designed to avoid excessive draw into corners that would result in locally thin areas. For this reason, blow molded products invariably have rounded corners. Another potential source of weakness is the pinch-off line. To compensate for this fact, it is common to program the parison to produce a thickened base. 

Why do blow molded products have rounded corners ... 

Vacuum forming has limitations due to the non-uniform wall thicknesses of its products. As the sheet is drawn into the mold, its thickness decreases, especially in the corners. For this reason, just as in blow molding, we design vacuum formed products to have rounded corners. If the depth of the cavity is excessive, walls can become locally so thin that they are unacceptably weak. One strategy that we use to alleviate this problem is to pump air into the cavity after the sheet has been clamped. This inflates the sheet, pushing it upwards and expanding its area approximately uniformly. When we subsequently apply a vacuum the expanded sheet is drawn back down into the mold. The finished product has a more uniform wall thickness than if we had applied the vacuum directly.

In Fig. 12.166 sphere and CDE calculations are compared with measurements on MgO cubes well dispersed in KBr neither is very satisfactory. The calculated position of peak absorption by spheres is fairly close to that measured but not coincident with it the CDE calculations show appreciable absorption over approximately the same frequency range as the measurements but no structure. If the optical constants we have used accurately place the Frohlich frequency, Fig. 12.166 suggests that neither spheres nor a broad distribution of shapes are good approximations for MgO particles. This is hardly surprising because electron micrographs reveal that MgO smoke is composed of cubes. These cubes are so nearly perfect that they have been used to quickly determine the resolution of electron microscopes degraded resolution results in apparently rounded corners.

The Problem You have a rectangular pool that s 40 feet long and 30 feet wide. You want to put in a cement walkway that s 6 feet wide on all four sides, and the corners will be 6-foot squares. How many square feet of cement will you need (Refer to Figure 19-6 which shows both the square corners for this problem and rounded corners for the next problem.)...

The use of TRDs has been facilitated by the use of fibre-optic cable assemblies (Section 6.12.4). This permits sensing in confined spaces as well as enabling the sensor to see round corners and into regions containing nuclear or electromagnetic radiation 36 . Low levels of source visibility can be overcome by employing two-colour or ratio sensors which measure radiation at two different wavelengths simultaneously. Such instruments can be used where dust or dirt obscures the source from the sensor.

Colors and impurities obviously filter out certain radiation bands. Increasing the thickness of a container will obviously increase the absorption of any given absorbed band. One of the most difficult items to measure is the effect of the container geometry on the exposure. Depending on the physical shape of the container and the angle(s) of incidence of the radiation (cosine law effect), radiation can be reflected or refracted by flat surfaces and possibly focused internally by rounded corners.

The moldability/1344 indicates the number of samples which, upon visual inspection, show flaws such as surface voids and rounded corners. Wire sweep and internal voids were determined by x-ray screening. These data may reflect a somewhat greater reactivity of the new molten resin. A further increase in resin viscosity may lead to wire sweep and other imperfections such as internal voids. A low resin bleed count supports this idea. (Resin bleed is resin material protruding onto leadframes beyond the rectangular shape of the resin mass). Linear devices were also molded over CuA leadframes at 175 and 150°C. The test yields were 98.0 and 98.8% respectively. These yields, as well as those obtained with A-42 leadframes (Table IV) are identical to the yeilds observed when commercial encapsulants are used.

A simplified schematic of the hierarchical planning mechanism of ES-EPA is shown in Figure 2. There are four representations of a plan with different abstraction levels Level 1, 2, 3 and 4. In this figure, the rectangular boxes represent specific tasks that can not be expanded any further, and boxes with rounded corners represent abstract components.
