Epoxy/activated carbon composites of particle sizes (60, 105, 150μm) and reinforcement weight percentages of (2, 4, 6 and 8) have been developed and evaluated for engineering applications. The physicomechanical properties were determined according to ASTM standard methods. Density decreased with an increase in reinforcement weight percentage. 2% weight increment of the particle sizes of the chemically activated carbon fillers yielded tensile and flexural strengths higher than that of the selected commercial brake pads (CB1) and (CB2), with the tensile strength of 4.84 and 6.58MPa, the flexural strength of 12.84 and 21.61MPa respectively while the hardness results compared well with the commercial brake pads samples. In general, from the standpoint of its tensile strength, %elongation at break, flexural strength, and hardness properties, these new formulations can find applications in aerospace and automobile industries where lightweight, high strength materials are sought after, hence a potential organic friction lining precursor for brake pad manufacture.

The main objective of this work is to understand how the tool wear and surface roughness are influenced by various cutting fluids and machining parameters in turning EN8 SAE/AISI 1040 steel. Cutting fluids should be chosen by acidic nature test and viscosity test. It should have proper lubricity and act as a coolant. Vegetable oils like groundnut, coconut, and sunflower are considered to check their properties. Among these oils, groundnut and coconut oils were selected based on their properties. Experimental studies on the performances of both newly developed environmentally friendly vegetable-based cutting fluids (coconut oil and ground nut oil) and commercial cutting fluids in turning processes were reported. Performances of cutting fluids were compared with respect to surface roughness, cutting and feed forces and tool wear during longitudinal turning ofEN8 SAE/AISI 1040 steel. Experimental results were also compared with dry cutting conditions. Based on the results, the best-cutting fluid was selected.

To investigate the solar air heater’s (SAH) effectiveness, experiments are conducted using flat plates and artificially roughened plate in terms of Inclined and Winglet baffles over the collector surface. This proposed system collector plate comprises Inclined and Winglet ribs and serves as an artificial roughness generator. Airflow rates of 0.01, 0.02, & 0.03kg/s are used in the experiment. To determine the improvement in the proposed work, the experimental results are compared with flat plate SAH. This proposed work offers greater efficiency, useful energy gain, and lower top heat loss than a conventional SAH. The airflow rate of 0.03kg/s gives the topmost efficiency and useful energy gain. The experimental day’s average efficiency of a SAH with Incline baffles is 32.6 %, 53.6 %, and 61.9 %, respectively, for the flow rates examined. For the same flow rates, it is 37.4 %, 29.6 %, and 24.39 % more effective than a flat surface SAH. For the same investigated air flow rates, the proposed system gains 37.7 %, 27.63 %, and 23.63 % more energy than flat plate SAH. Substantial reductions in Top losses of up to 8.20 %, 6.55 %, & 7.65 % have been reported at the specified flow rates. Energy metrics and economic study performed shows the payback time, Production factor, Life cycle conversion efficiency and economic values of the proposed SAH is optimum.

Food is an essential need of life. It is how man is fed and reinforced to complete his everyday exercises. The requirement for nourishment for the upkeep of man has set horticulture in charge of man's issues on the planet. With a quickly expanding populace on the planet, man has imagined more up-to-date and inventive ways of developing yields. This development is gathered in country areas of nations all over the planet; yet with the monstrous urbanization occurring in this present reality, it is turning out to be progressively hard to have good horticultural produce that will cook for the gigantic populace. Accepting Nigeria as contextual analysis, the expanded urbanization has put a gigantic expectation ashore, energy and water assets inside the metropolitan region of the country. The larger part of the food eaten in the metropolitan regions is developed in the provincial regions. This framework anyway requires longer transportation times from the provincial areas to metropolitan regions, leading to pollution and deterioration. This examination paper gives an answer in which food harvests can be developed effectively in the metropolitan regions by planting in upward stacked layers to save space and utilize negligible energy and water for water systems.

Glass fibre reinforced polymer (GFRP) composite materials replace traditional engineering materials due to their properties. Accordingly, the need for accurate machining of composites has increased enormously. The advantages include high strength to weight ratio, high fracture toughness and excellent corrosion and thermal resistance. Even though the moulding process may produce GFRP parts, they require further machining to facilitate dimensional control for easy assembly and control of surface quality for functional aspects. The material removal mechanism is different from that of machining single-phase materials, such as metals. GFRP are extremely abrasive when machined. Thus, selecting the cutting tool and the cutting parameters is very important in the machining process. The machinability in turning operations of glass fiber reinforced plastics (GFRP) will be investigated by the super-hard cutting tool (PCD and Ceramic Inserts). A plan of experiments will be performed on controlled machining with cutting parameters prefixed in the workpiece.

The term composite is a combination of two materials with different physical and chemical properties. When combined, they create a specialised material to do a certain job, for instance, to become stronger, lighter or resistant to electricity. They can also improve strength and stiffness. Metal matrix composites have much improved properties, including high tensile strength, toughness, hardness, low density and good wear resistance compared to alloys or any other metal. Aluminium alloys are becoming important today, especially in the automobile, space and electrical industries. Unfortunately, due to poor wear resistance, aluminium alloy can deteriorate quickly. So the present investigation aims at developing Aluminium 356 alloy (AA356) composites reinforced with 5 wt.% Zirconium Silicate (ZrSiO4) with better wear resistance. The composites have been fabricated using the ‘stir-casting’ method in which the particles were added to molten metal during the stirring process at a rotating speed of 700 rpm. A wear test has been performed on a pin on the disc apparatus. Three process parameters have been considered: normal load, sliding velocity, and sliding distance at three different levels. An experimental plan has been made using Taguchi’s L9 orthogonal array table. The output responses such as wear rate and coefficient of friction have been considered for the investigation. Regression models have been generated for each output response. Using the generated regression models, one can predict the value of the output parameters even without actually performing the experimentation within the range of input factor combinations.

A rotary tiller or rotavator is active tillage equipment used to prepare farmland for sowing seeds, weeding, mixing manure and fertiliser into the soil, crushing soil blocks, etc. Compared with conventional farming, the advantages of this equipment are rapid seedbed preparation and reduced draught. Nowadays, the utilisation rate of rotary tillers has increased. However, the blades are the key component that engages with the soil in the rotary tiller. These blades interact with the soil differently from ordinary ploughs and bear impact loads and high frictional forces, which eventually generate unbalanced and uneven forces on the entire rotary tiller. As a result, the blade faces significant wear. Therefore, it is necessary to optimise the design of the blades to minimise wear and enhance the service life. In this research work, design optimisation was carried out towards improving service life.

The aim of this article is to carry out analysis to enhance the performance of the ferro fluid lubricated porous step bearing. The porous coating is assorted to the lower flat impermeable surface. A step is there in upper surface which approaching to lower surface. This study considered that magnetic field is flexible and oblique to the lower surface. By considering Jenkins Model, expressions for pressure and load capacity are obtained. The non-dimensional load capacity is also calculated for various parameters. Based on results, it is observed that load capacity increases if suitable step size is considered. Also, comparison between R. E. Rosensweig Model and Jenkins Model is carried out. Finally, it is advised to design a porous step bearing, one should consider Jenkins Model over R. E. Rosensweig Model.
本文的目的是对提高铁流体润滑多孔台阶轴承的性能进行分析。将多孔涂层组合到下平面不透水表面。在上表面有一个台阶向下表面靠近。本研究认为磁场是柔性的，并向下表面倾斜。考虑Jenkins模型，得到了压力和承载能力的表达式。计算了各种参数下的无量纲承载能力。结果表明，如果考虑适当的步长，则负载能力增加。并对R. E. Rosensweig模型和Jenkins模型进行了比较。最后，建议设计多孔阶梯轴承，应考虑Jenkins模型而不是r.e. Rosensweig模型。
