Small edges

The end effect for charges of L/d 3.5 has also been shown in shaped-charge and other studies to vary ca as the cube of the effective diam d of the charge which takes into consideration a small edge effect (qv)... 

To create the 4-D viewer, he uses three trapezoidal-shaped mirrors, each with dimensions of 12" X 5" X 2" (In other words, the two small edges are 12 inches... 

The methyl ethers of many aryl carbinols cleave in Et20 with liq Na-K alloy or with potassium powder (reaction of the latter is facilitated with the aid of small-edged pieces of quartz glass to cut through incrustations on the potassium on shaking), e.g. ... 

Where anehors are used to transfer shear, reinforcement is typically required, since it is generally diffieult to develop the anchor loads in the concrete member only. This is because of limited eonerete breakout strength due to small edge distances and anchor spacing. Shear reinforeement should be designed to carry the entire shear load, exeluding any contribution from concrete. Stmt-and-tie models can be used to analyze shear transfer to elosed ties. 

In the fourth place, it is necessary to furnish the lower end of the tube with an iron collar, giving its lower contour a thin edge approximately 3 millimetres wide. This addition aims to oppose the oil mass rising in an irregular way up the external surface of the tube here, as in the experiment of 14, the small edge stops any external rise of oil, and obliges the mass to take a perfectly symmetrical position under the tube. 

If n indicates the number of the side faces of the prism, 1° the number of the small edges forming the apex of each of the two basal pyramids, and consequently also the number of the longitudinal films going from the small edges of one of the pyramids to those of the other, is n — 3 2° the number of the systems of this kind realizable in the same frame is equal to that of the different open shapes that one can form with n —3 small edges, under the condition that there are never more than three meeting at the same point.
