Gravity a Viscoelastic Mechanics of the Universe

Anwar Wali Gutti — 2019-09-15

This paper mathematically proves that gravity is a viscoelastic property. From the Newton’s
law of gravitation, a viscoelastic equation is been derived which is similar to one obtained
from the Newton’s law of viscosity. From the viscosity equation, the present strain rate of the
universe is calculated, and at the same time the Hubbles constant for the expansion of
universe is converted into an equation of strain rate and both the values are compared. The
value obtained from the viscosity equation is in agreement with the Hubble’s constant. Also,
the equations derive are based on the Gough-joule effect of negative coefficient thermal
expansion of the space time fabric. Hence, the expansion of universe is explained as a viscous
flow of gravity caused due to yielding which was initiated during the inflation period after the
big bang.

Design and Fabrication of Motorized Stirrer Mechanism for Stir Casting Furnace

Ashok Kumar M S — 2019-11-11

Composite materials are of high demand due to their superior strength and stiffness, metal
matrix composites (MMCs) are used for applications in the automotive and aerospace
industries. The preparation/fabrication of the composite materials depend on the application
of the MMCs. Among the available processing techniques, an economical way of producing
metal matrix composite is the casting or liquid processing technique which involves
incorporation of the particles into the liquid metal. Researchers have found that the casting
process yields composite materials with good mechanical and wear resistance properties.

Astromechanic Theory, an Application of Mechanical Engineering Principles to Relativity Theory

Anwar Wali Gutti — 2019-10-11

The following research paper uses plasticity theory of deformation to describe the yielding of space-time fabric (i.e., the increase in the area of the space time fabric without any application of force) on a stress strain curve. It considers the space-time fabric as an elastic material undergoing deformation in form of yielding, which also explains the reason of expansion of the universe. In this paper a mechanical prospective is applied to the relativity theory to explain the mechanics of the space time fabric in a very practical sense. Calculus of variation is used to mathematically derive the boundary conditions before big bang. The research paper in detail explains the reason of occurrence of big bang using the concept of space-time fabric and describes the elementary particles in form of 3-dimensional crushed energy fabric.

Wind Induced Vibration Analysis of Hat Sectioned Highway Sign Pole for Legibility

Atul V. Karanjkar — 2019-11-28

Transportation authority always tries to improve the road safety. As the role of the road
signs used by them is; to prove key information through warning, guiding and regulating the
road riders, the highway sign poles are vital element of road transportation system. It
consists of a sign board supported by hat sectioned beam. Their main function is; to assist
the driver to drive the vehicles appropriately and safely. So they are designed for all season
situations. A problem in traffic sign readability may leads to unsafe driving behaviors. Also
any flaws in it lead to an accident possibility of the road vehicles. This paper deals with an
effect of stormy winds that causes undue vibration and has a detrimental effect on drivers’
vision. A methodical approach is applied that includes vibration analysis of hat sectioned
sign pole to ensure its frequency within safe limit specified by the concerned regulatory
bodies. Numerical method is used to verify the obtained result.

Occupational Hazards in the Textile Printing Process

Om Kumar CS — 2019-10-26

The base of this research the work involves in the printing units without using proper PPE
resulted in various types of physical, chemical and biological hazards. Due to these
problems, the workers are affected by skin were itching, dry skin, cracks and pimple acne
owing to the exposure of chemicals. Body problems comprised of pain, stiffness, and tremors
in hand and pain in the elbow due to the suitable performance and lower parts. In results, it
concludes that people working near the units suffering from many physical problems such as
head pain, eye-irritancy, and difficulty in breathing and overflow of the drainage pipes from
printing units, polluting the drinking water by mixing of chemical dyes.
