Published: February 2021

AbstractInvestigation and assessment of mechanical properties for FRP (Fiber Reinforced Polymer) composites have been instrumental in qualifying it for the final use. Pronounced among mechanical properties is flexural strength which diversifies with varying test span length, Specimen depth and temperature for different materials. Current work focuses on unearthing the optimum span length of epoxy Glass fiber reinforced composites for which flexural strength is to be scrutinized. Investigations for flexural test in accordance to ASTM Standard D790 are executed by altering the span lengths to acknowledge the functioning of the flexural modulus and strength thereby acquiring an optimum span length, which, can be employed by the composite designers and manufacturers to engineer meliorated testing procedures. From the experimental results it is found that the composite failed by shear mode at lower span lengths.

Abstract
The fabrication of composites using synthetic fibers such as carbon, glass, aramid, etc is expensive because of higher cost of individual fibers. This requires alternative materials development with less production cost. Naturally available jute and bamboo fiber were used as reinforcement in this present work. Natural fibers are inexpensive as compared to synthetic fibers and has emerged as a renewable and cheaper substitute to synthetic materials such as glass, carbon and aramid, which are used as reinforcements. In this work, the objective was to develop, investigate and analyze the tensile behavior of a composite material using bamboo fiber and jute fiber sandwich type composite. The results were studied and compared with the composite of bamboo fiber with epoxy resin. The experimental results shows that hybrid composites is having significantly greater values as compared to monolithic composites. The primary objective of the present work is to find out the effect of jute fiber on tensile properties of jute and bamboo reinforced hybrid composite.

Published: February 2021

Abstract
Disc brakes are used in vehicles to slow down or stop the angular and linear velocity of the wheels that uses calipers to squish a set of two similar pads versus the disc. During this process, the disc or rotor gets heated up due to friction from the pads. Frequent braking will cause abundant heating of the disc or rotor. Therefore, it is crucial in quick dissipation of heat from the rotor disc. Keeping this in mind, a comparison between the different materials is modelled in Creo parametric and it is analyzed in ANSYS 2019 R3, in this paper transient analysis of Cast Iron,Tungsten carbide and Hafnium carbide is modelled and analyzed using Creo and ANSYS 2019 R3 respectively. The best among them is selected as a material for the disc rotor.

The development of a new indoor mobile robots navigation method is one of the emerging areas in the engineering field. The robot device consists of a tag sensor RFID, a laser range detector and a handheld platform and ultrasonic sensors. Mobile robot navigation systems are important for ensuring a more reliable and precise protection and stability of human robot activity. The device needs to be developed using the latest RFID technologies to reduce the expense and precision of current navigation systems containing more sensors to achieve the necessary characteristics. The labels have novel distinguishing pieces of proof inside the recollections, and the recollections might be perused from a few meters away. RFID labels are used as a landmark for the global route plans and as course guidance to a target, the topological relationship map showing the correlation of distributed tags to the environment is used. The robot runs automatically through range data for scanned to locate a mark, after returns to movement after next through charts of topological. A precise means of estimating the position depends on the points of interest. Windows, ventilators, walls are needed for landmarks for buildings.

Abstract
Crushing is the process of reducing the size of ore into definite smaller sizes. Cone crusher is a size reduction mechanical equipment which crushes the large sized limestone and dolomite particles by squeezing it between gyrating spindles. Crusher must be mounted on a frame to be coupled with the motor drive. A base frame is designed in such a way that it acts as a platform for motor and cone crusher. As the motor and cone crusher performs its operations at higher frequencies, the base frame tends to fail because of the mechanical vibrations of system and larger torques induced in the mechanism between cone crusher and base frame. Failure of base frame is prevented by using the better I-Section beams whose strength and rigidity is high. Compensators absorbs the vibrations and helps the system to attain equilibrium. A set of compensators are placed all along the I-Section. These compensators are grounded using mechanical fasteners. In the course of this research it is observed that beam has a larger tendency of failure at certain cross sections. Stiffeners could be inserted at those locations for the better rigidity, support and strength of the entire structure. Modelling and Analysis is done individually to motor frame, crusher frame and on the entire assembly. An optimum system frequency was used, for the assembly to be at equilibrium in the dynamic conditions.

Abstract
Technology has blended itself with the everyday life of humans. People aren’t finding greater efficiency despite the field of science and technology has progressed well. Traditionally goods are moved and distributed in and around an industry manually by humans. By using an automated material handling system this problem was reduced to a certain percentage. Even though there is no efficient method to deliver the products directly to the end-user like the patients in the hospitals. So,a robotic system that transports materials all over the workplace has been designed. The serviceability of the system is based on themaster-slave concept. This system can be used in mining operations to carry materials on a rail.To make the design economical, low-cost parts are used which makes it ideal for production on an industrial scale which will aid in many applications like drug delivery systems in hospitals and also material carrying robots in mine.

Abstract
This paper presents the control of suddenly expanded flow using four microjets at the base recirculation zone for a diameter ratio of 1.8. Eight Mach numbers are considered for investigations from 1.25 to 3. The NPRs for which the tests were conducted were from 3 to 11. The duct length considered was L = 10D to 1D. This article has shown only selected results when there is significant variation in the duct's flow field; only those cases are considered. For most of the cases, the flow remains identical with and without control. For Mach M = 1.25 to 2.5, the control results in decline in the duct's pressure when the flow is within the reattachment length. Later there is a progressive rise in the duct pressure. However, the trend is reversed at Mach M 3.0. The least duct stretches necessary intended for the stream to continue to relate to the pipe is L = 1D, 2D, and 3D for the study's Mach number.
