Angular position

Because of the variation in potential energy with the angle of rotation, not all locations on the rim of the cones in Fig. 1.7b are equally favored. The probability of a particular angular position depends on the potential energy at that location, V, and an averaging procedure which considers this angular variation must be used to modify Eq. (1.60). The result of this procedure is... [Pg.58]

The field phasor is a continuously rotating phasor in the space, whose angular position keeps changing with the position of the rotor with respect to the stationary stator. Let the rotor field displacement under the stationary condition with respect to the stator be denoted by angle /3as shown in Figure 6.11, This displacement will continue to change and will rotate the rotor (field frame). All the phasor quantities of the stator arc now expressed in terms ol the field frame. Figure 6.11 shows these two equivalent stator side phasors transformed to the rotor frame. [Pg.107]

The positional toleranee on a 10mm dimension was 0.1 mm (toll), providing an angular position of 0.6 ". Additionally, the widths of the reeesses needed to be held to 4 0.08 mm (tol2), the dimensional toleranee on the faees to 1 0.07 mm (toll) the depth to 10 0.12 mm (to ). Also, the thin seetions of the hub gave two geome-trieal eoneerns as these vanes were on the limits of plastie flow and distortion was likely on eooling. [Pg.89]

The homolysis of tertiary hypochlorites for the production of oxy radicals is well known." The ease with which secondary hypohalites decompose to ketones has hampered the application of hypohalites for transannular reactions. However the tendency for the base-catalyzed heterolytic decomposition decreases as one passes from hypochlorites to hypobromites tohypoidites. Therefore the suitability of hypohalites for functionalization at the angular positions in steroids should increase in the same order. Since hypoidites (or iodine) do not react readily with ketones or carbon-carbon double bonds under neutral conditions hypoiodite reactions are more generally applicable than hypochlorite or hypobromite decompositions. [Pg.246]

The second special case is an orthotropic lamina loaded at angle a to the fiber direction. Such a situation is effectively an anisotropic lamina under load. Stress concentration factors for boron-epoxy were obtained by Greszczuk [6-11] in Figure 6-7. There, the circumferential stress around the edge of the circular hole is plotted versus angular position around the hole. The circumferential stress is normalized by a , the applied stress. The results for a = 0° are, of course, identical to those in Figure 6-6. As a approaches 90°, the peak stress concentration factor decreases and shifts location around the hole. However, as shown, the combined stress state at failure, upon application of a failure criterion, always occurs near 0 = 90°. Thus, the analysis of failure due to stress concentrations around holes in a lamina is quite involved. [Pg.337]

However, the horizontal reading on one bearing will not show the same phase relationship as the vertical reading on the same bearing. This is due to the pickup axis being oriented in a different angular position, as well as the phase adjustment due to possible resonance. For example, the horizontal vibration frequency may be below the horizontal resonance of various major portions of machinery, whereas the vertical vibration frequency may be... [Pg.940]
