It appears that at the application of the torque of 3789 Nm torsion angle is equal to 1.
Since during analysis the model in rear axle was fixed absolutely rigidly, we can conclude that torsion angles of the load-body structure and the front axle are equal.
Gradually increasing the torque, the difference of equivalent stress and load-body structure torsion angles between the results of the models studied stabilizes.
For the purposes of this discussion, assume that the molecular structure has been parameterised in terms of variable torsion angles only, i.
In this way, the molecule was parameterised as a rigid fragment with only two optimisable torsion angles connecting the -N(C[H.
The 6-position Cl in the current orientation would have a major Van der Waal contact with Y20, and because there are three substitutions at the ortho positions (2,6,2') on the phenyl rings, this molecule would most likely have to have a torsion angle near 90[degrees] between the two phenyl rings.
Each pair of adjacent spheres is bonded, and can stretch, bend, and twist by changing the bond distance, bond angle, and torsion angle, respectively.
t] of the torsion angle between adjacent spheres exerted on each sphere to recover the equilibrium torsion angle
Likewise, if the twisting strength of the fiber is [Mathematical Expression Omitted], the occurrence of fiber fracture can be defined as the moment when displacement of the torsion angle between adjacent spheres equals the following value
8]), the energy is minimized by changing all torsion angles of the molecules.
Thus we can conclude that the crankshaft motion of the bisphenol A unit does not affect the torsion angles of the neighboring triazines, but such a motion requires a cooperative motion of the following connected triazine rings.
