In this work, as a continuation of rigorous solutions of the mathematical pendulum theory, calculated dependences were obtained in elementary functions (with construction of plots) for a complete description of the oscillatory motion of the pendulum with determination of its parameters, such as the oscillation period, deviation angles, time of motion, angular velocity and acceleration, and strains in the pendulum rod (maximum, minimum, zero, and gravitational). The results of calculations according to the proposed dependences closely (≪1%) coincide with the exact tabulated data for individual points. The conditions of ascending at which the angular velocity, angular acceleration, and strains in the pendulum rod reach their limiting values equal to (Formula presented.) and 5m1g, respectively, are shown. It was revealed that the angular acceleration does not depend on the pendulum oscillation amplitude; the pendulum rod strain equal to the gravitation force of the pendulum Rs = m1g at the time instant (Formula presented.) is also independent on the amplitude. The dependences presented in this work can also be invoked for describing oscillations of a physical pendulum, mass on a spring, electric circuit, etc. © 2014, Pleiades Publishing, Ltd. Source

Hydrodynamic calculation of potential flow from the impact of a plate onto water was reported. The plane problem of a plate (2a in width, d thick, and with a density p) falling onto the smooth surface of an ideal (incompressible) fluid of infinite depth with the velocity was considered. The problem is solved using the theory of a function of a complex variable by the method of consecutive conformal maps of the physical flow region to the complex-potential region. The obtained rigorous hydromechanical solution makes it possible to find all necessary parameters of the potential flow arising at the moment of the plate impact onto water for the full (unit) value at an arbitrary point of the flow region.

The measurements of the atmospheric electric field potential gradient are analyzed simultaneously at the two high-mountain stations in the vicinity of Mt. Elbrus: Cheget Peak and Terskol Peak, as well as the Kyzburun mountain station located at the end of the Baksan ravine. A global component in the diurnal variation in the electric field is revealed: the morning minimum (01-04 UT) and the evening maximum (19-21 UT), which conforms to the unitary variation in the ionospheric potential, as well as the daylight maximum (08-12 UT) caused by the action of the local generators in the surface layer. The features of the seasonal variation in the electric field are studied. © 2015, Pleiades Publishing, Ltd. Source

Developed is the kinetics of condensation processes in disperse systems formed during the dispersion of crystallizing reagents using an artillery method; a simple scheme of the Brownian coagulation is generalized for such systems. Computed are the yield of the number of crystals from one gram of the crystallizing reagent and their mean radiuses. For AgI these values are of the order of 1012 and 10-7 m, respectively. © 2012 Allerton Press, Inc. Source

Considered are the processes of condensation in the cloud of explosive gases containing the vapor of crystallizing reagent. It is demonstrated that the stable condensation nuclei of critical size originate mainly at the moment of the transition of explosive products into the ideal gas. The rate of origination of embryonic reagent particles capable of further growth is computed for a number of explosive substances on the basis of the Volmer theory. © 2012 Allerton Press, Inc.
