Rotational strengths reduced

As the appHed field is reduced, the iaductioa does aot retrace curve 1 but foUows curve 2 as the domaias at first merely rotate back to the aearest local easy axis directioa. The value of B at i/ = 0 is the remanent iaductioa. At H = which is the coercive-field strength of coercive force or... 

The moment of inertia 1 determines the rotational constant 0 = h /IT, which is the parameter that controls the strength of quantum effects. The other parameter of the model, which is the quadrupolar coupling constant K, can be conveniently taken as the energy and temperature scale. We can thus reduce all quantities related to energies by K, and define, e.g., the dimensionless temperature = k T/K, energy = E/K, and rotational... 

These strengths tpply only when t test is conducted with both ends fixed. When in use, the strength of these ropes may be significantly reduced if one end is free to rotate. 

Doubling the separation of polar molecules reduces the strength of the interaction by a factor of 26 = 64, and so dipole-dipole interactions between rotating molecules have a significant effect only when the molecules are very close. We can now start to understand why the kinetic model accounts for the properties of gases so well gas molecules rotate and are far apart for most of the time, so any intermole-cular interactions between them are very weak. Equation 4 also describes attractions between rotating molecules in a liquid. However, in the liquid phase, molecules are closer than in the gas phase and therefore the dipole-dipole interactions are much stronger. 

It is important that connections for blast loaded members have sufficient rotation capacity, A connection may have sufficient strength to resist the applied load however, when significant deformation of the member occurs this capacity may be reduced due to buckling of stiffeners, flanges, etc. Figure 10.1 is an example of a connection design for large rotation capacity.
