Relative strength, characteristic

Characteristics of the air jet in the room might be influenced by reverse flows, created by the jet entraining the ambient air. This air jet is called a confined jet. If the temperature of the supplied air is equal to the temperature of the ambient room air, the jet is an isothermal jet. A jet with an initial temperature different from the temperature of the ambient air is called a nonisother-mal jet. The air temperature differential between supplied and ambient room air generates buoyancy forces in the jet, affecting the trajectory of the jet, the location at which the jet attaches and separates from the ceiling/floor, and the throw of the jet. The significance of these effects depends on the relative strength of the thermal buoyancy and inertial forces (characterized by the Archimedes number). 

A key element in the experimental determination of the stiffness and strength characteristics of a lamina is the imposition of a uniform stress state in the specimen. Such loading is relatively easy for isotropic materials. However, for composite materials, the orthotropy introduces coupling between normal stresses and shear strains and between shear stresses and normal and shear strains when loaded in non-principal material coordinates for which the stress-strain relations are given in Equation (2.88). Thus, special care must be taken to ensure obtaining... 

The relative strength of the shunt and series fields of the motor determines to what extent the motor approaches the shunt or series characteristics. 

The strength characteristics of composites with an anisodiametric filler depend heavily on the orientation of the reinforcements relative to the direction of load application. For fiber-filled materials this has been observed in a number of works (cf., e.g. [133,153-157]) illustration can be borrowed from [157] the data of which are presented as Table 3 below. 

Unlike the relation between brisance and PCJ, expl strength is not readily related to some detonation characteristic of the explosive. Attempts to relate strength to detonation energy are not wholly successful. Relative strength, based on ballistic mortar tests, correlates rather well with computed nRT, where n T are the computed moles of gas and detonation temp of the explosive, and R is the gas constant. Although n T can differ appreciably with the equation of state used in the computation, it appears that ratios of nRT (at least for similar explosives) do not suffer from this drawback... 

The formation, the characteristic directionality and the relative strengths of the noncovalent bonds that have been discussed can be explained in a very direct and straightforward manner in terms of electrostatic attractions between positive a-holes and negative sites. The a-hole concept is, moreover, fully compatible with... 

LLDPE is made by a catalytic process very similar to that for HDPE, but it is a softer polyethylene than HDPE with properties similar to those of LDPE. Its properties are achieved by inclusion of comonomers such as butene or hexene. A relatively disordered crystalline state is obtained by introducing many short branches into an otherwise highly linear molecule. Thus, the less expensive equipment of the HDPE process can be used to make a product having the greater flexibility and impact strength characteristic of LDPE. 

If the uniformity of the plastic foam relative to strength characteristics is determined, the left-hand side of Eq. (5) is the ratio of strei th at given probability a to the mean value of strength and... 

It was thus postulated that the liquid phase mole fraction X3 of the solid solute in the ternary system is proportional to the partial molar volume fraction (PMVF) of the solvent in the binary solution. In other words, the solvent capacity of the C02-diluted solution is due to the solvent s contribution to the molar volume of the solution. This new term, PMVF, defined as [(1 — Xi)v2/v], is thus a characteristic parameter depicting the solvent capacity of the binary (C02-diluted) solvent mixture for the solid solute, and it varies between 0 and 1. Figure 24 shows that the PMVF of the solvent decreases with increasing CO2 mole fraction, as does the solvent capacity for the solid solute (57). The retention of solid molecules in the liquid phase is primarily attributed to the capacity of the partially surrounded solvent molecule to retain its affinity for the solute molecules. In other words, the number of solid molecules that can be accommodated in the vicinity of the solvent molecules in the C02-diluted solution phase is attributed to the relative strength of the clustered solvent molecules, which are only partially available for the solid solute molecules. 

The most indicative deformation and strength characteristics of inhibiting films are the breaking tensile strength and relative elongation at rupture [1]. The methods for their determination also have respective standards [144-146]. Films intended for wrapping bulky or sharp-edged hardware have to meet the requirements on resistance to rupture [1,147-151] and puncture [1,152]. 

The solute descriptors [R, Jt, a, p, V] are characteristic parameters of the chemical. Their values will not change when the chemical is transferred from one medium system to another. Each of the solute descriptors represents the relative strength of a specific type of molecular force of the chemical ...
