We study exact solutions of nonlinear electrodynamics coupled to 3D gravity with torsion. We show that in any static and spherically symmetric configuration, at least one component of the electromagnetic field has to vanish. In the electric sector of the theory, we construct an exact solution, characterized by the azimuthal electric field. When the electromagnetic action is modified by a topolo...

It is shown that in static and spherically symmetric configurations of the system of Maxwell field coupled to 3D gravity with torsion, at least one of the Maxwell field components has to vanish. Restricting our attention to the electric sector of the theory, we find an interesting exact solution, corresponding to the azimuthal electric field. Its geometric structure is to a large extent influen...

The paper shows an algorithm for determining the load on electric motor of run-out conveyor starting from determination first moment no operation during slab conveying, slipping torque rollers along surface conveyed billet and ending with choice motor. It also covers strength calculations roller, which includes calculation moments forces acting roller its supports, static torsion strength, defl...

In this paper, we present the dynamic response of commercially pure copper subjected to combined tension-torsion loads representative real case impact scenarios. Experiments were conducted both quasi statically, at a strain rate equal 10?3 s?1, and dynamically rates in region between 500 s?1 1000 s?1. All high experiments using novel Split Hopkinson Tension-Torsion Bar instrumented with high-sp...

The testicular torsion which is typically seen in prepuberty is very rare in the early neonatal period; prenatal diagnosis is difficult. Herein, we report a five day-old male neonate with swelling and erythema of the right scrotum.  Following Doppler ultrasound suggestive of testicular torsion, surgical exploration was undertaken. There was gangrene of the right testis with discoloration and ne...

As an important machine for agricultural application, the upland gap self-propelled sprayer is environmental friendly and operates efficiently. In this paper, chassis frame, which one of components sprayer, studied a disconnected longitudinal beam frame with X-shaped reinforcement was designed. The static mechanical properties under bending, torsion, emergency braking turning conditions are ana...

Abstract The rigidity in bending of a flexible link (is an important characteristic that should be considered during regular service conditions. tension and with torsion wire ropes are also significant factors. This study proposed method to calculate the vectors generalised forces links. One causes torsional stresses power plant underwater tethered systems is interaction ship equipment, such as...

A novel experimental procedure for the testing of ceramic coatings in quasi-static and dynamic torsion is presented. The tests were performed on a Kolsky bar apparatus modified for torsion loading. High-speed photography was used to take snapshots of the surface of the specimen gage during loading, and digitally correlated to determine the full displacement and strain fields. Microand nanoAl2O3...

The Einstein-Cartan equations in first-order action of torsion are considered. From Belinfante-Rosenfeld equation special consistence conditions derived for the parameters relating them to metric. Inside matter is given by spin which leads an extended Oppenhaimer-Volkov equation. Outside a second solution found besides torsion-free Schwarzschild one with completely determined metric and vice-ve...
