The change in the power factor from the coefficient of rigidity of the loading [k.sub.l] depends on how the latter differs from the value corresponding to the change in the sign of the reactive resistance, i.e.
here E is Young modulus of material; f is cross area of every T-belt; [K.sub.c] is coefficient of rigidity of elastic layer, formed with web-posts; I is moment of inertia of beam calculated for weakened by opening section; i is proper moment of inertia of T-belt located above opening; M is flexure moment.
Coefficient of rigidity [K.sub.c] can be calculated as:
Using this tailing for tests, it was determined that it becomes Bingham plastic over 18% of volumetric concentration with extreme high coefficient of rigidity and yield stress corresponding to increasing concentration (Table 11).
Generally, these suspensions become non-Newtonian fluids over 20% of volumetric concentration and the viscosity like parameter (absolute viscosity--Newtonian, coefficient of rigidity Bingham plastic, consistency index--Pseudoplastic) gets exponentially higher.
where [C.sub.e] is the slope of the electromagnet pulling characteristic; [C.sub.s] is the coefficient of rigidity of the spring; Cc is the coefficient of force of friction.
(6.) The accuracy of direct-current milliammeters in which the entire current to be measured flows through the moving coil is almost independent of changes of the instrument temperature, because (1) no change in the distribution of the measured current between the moving coil end a shunt circuit around it can occur as a result of change of temperature; (2) the small temperature coefficient of magnetic flux density in the air gap (about 0.01 to 0.03 percent per [degrees] C.) tends to offset the temperature coefficient of rigidity of the springs, which is about 0.04 percent per [degrees] C.
To complicate matters further, sludge of three percent solids behaves more like a "Bingham Plastic" and the flow of such a material is described by two constants - the yield stress and the coefficient of rigidity. Water, a "Newtonian" fluid is defined by the one constant, viscosity.
where [DELTA][z.sub.13](t), [DELTA][z.sub.12] (t) are the oppositely directed movements of the BPA and the FPA relative to the inductor along the z axis; [m.sub.2], [m.sub.3], [m.sub.e] are the masses of the FPA, the BPA and the striker, respectively; [K.sub.T] is the coefficient of dynamic friction; [[gamma].sub.a] is the density of medium of displacement; [[beta].sub.a] is the aerodynamic resistance coefficient; [D.sub.ex m] is the maximum armature diameter; [K.sub.P] is the coefficient of rigidity of the object of action.
The striker has a mass [m.sub.e]=0.45 kg; coefficient of rigidity of the object of action [K.sub.P]=3 x [10.sup.7] N/m.
