Hand calculations, finite element (FE) analysis and experimental validation of chassis mounted platform design for defence and commercial off-road vehicles have been attempted in this work. The work was commenced with the thorough study of platform configuration, loading pattern, platform mount location & configuration on the vehicle chassis and relevant vehicle characteristics. Calculation of section modulus, shear force and bending moment of various structural members under specified loading has been carried out before proceeding with the FE modeling and analysis of platform. FE model of the chassis mounted platform has been made using shell elements and the boundary conditions have been imposed based on the loading pattern with an assumption of rigid vehicle chassis. Static and gradient analyses of the platform have been carried out for full scale and reduced scale prototype FE models. Experimental strain measurement at critical locations under different static and gradient loads has been carried out for design validation of chassis mounted platform using the scaled prototype. Close correlation has been found between the experimental stress values and FE stress analysis results for static and gradient load conditions. From the entire load tests conducted, it is observed that the strain values in rear portion are less as compared with those in front and mid portions of the platform in-spite of the rear overhang provision.

By continuous and rapid growth in industrialization as well as population, the agricultural lands are also becoming less and less continuously day by day which results in increase in the population of small land holders. In addition to this, because of continuous decreasing production the youth of the villages are also migrating in big cities for the employment, resulting decreasing manpower essential to perform various seedbed operations in the villages. Hence, it is the need of time for small farmers having small agricultural land and having less crop production to introduce the cost-effective farm mechanization so that they can improve production rate. Rotavator is the best option available to achieve this landmark as it is already proved that seedbed prepared by using rotavator gives highest benefit to cost ratio. For this experimental study the whole land of 9 acre area is divided into 18 plots of equal size in area. The combination of method of seedbed preparation and use of fertilizers were the preliminary criteria. The categories of fertilizer according to quantity are discussed earlier which are 50kg, 35kg and 65kg per acre respectively. The quantities of organic fertilizer used are 45kg and 60kg per acre of agricultural land for both seedbeds which are prepared manually and by using rotavator. The highest production of Pigeon Pea was obtained of 814kg was from the plot whose seedbed is prepared by using agricultural machine called rotavator and organic fertilizer; next highest production is obtained of 802 kg from the plot whose seedbed is prepared by using rotavator and the fertilizer used was chemical fertilizer. The minimum production of Pigeon Pea which is 690 kg was obtained in the plot whose seedbed was prepared manually and chemical fertilizer was used.

The various root causes of the failure occurred within the structure, the fortification on its failure, anatomy of the structural repair, the exclusive facts associated with innovative methods and protective treatment and lots of a lot of things are mentioned and presented during this project report. The target of building maintenance to form the building and their connected services are in the secure and guarded condition, to grant guarantee that the condition of building meets all legislative standards and requirement to perform the upkeep work indispensable to uphold the worth of physical assists of the building and additionally to accomplish the work essential to keep up the prevalence of the building maintenance. In a world today main problem is corrosion its losses economic and life. Corrosion can be prevented but not long time. Hence, we find out new treatment called as Sanjivani, and it is best for corrosion removal in current time comparatively other methods. Comparison analysis and test conducted result and equation and formula and whole procedure is given in our research paper. This is newly invented by us, still test going on it, it is future of maintenance repair and biggest assets war again corrosion. We have included various prevention measures and corrosion removal techniques used in industry and market currently and we have analyzed it by our point of view and given diagrammatic representation of methodology in form of flow chart and various apparatus used its benefits over existing methods advantages and old principle required for our test equation and derived our results and conclusion using standard norms.

Methanol (CH3OH) and ethanol (C2H5OH) have came to limelight now-a-days because of their property of less polluting emittants and thought of as extremely economical due to its swish operative capacity. Low particulate level and soot free emission can also be obtained due to presence of oxygen in these fuels. We can obtain a considerable fuel efficiency and sound mileage if we double the carbon in ethanol which contains more energy. The structure is more similar to iso-butanol. Iso-butanol is unique in alcoholic fuels due to its equatorial affinity for water. The worldwide energy policy also aims to reduce greenhouse gas emissions occurred due to traditional fuels and thus developing renewable energy became an important part of this policy. Now-a-days transport sector has decreased its reliance on oil which generally contributes to hazardous environmental impact and to achieve this some alternative transport fuels such as biofuels, hydrogen and natural gas emerged up as a helping hand. Blending methanol into diesel and gasoline permits the mixture to possess an entire combustion with the presence of oxygen which increases its combustion efficiency and reduces greenhouse gas emission. Gasohol- a blend of gasoline and 10%methanol is available at plenty of petrol service stations as a regular automobile fuel within the United States. Brazil has successfully implemented and used methanol in terms of spark ignition engine operations as a fuel. Methanol has emerged up as a sustainable fuel for IC engines in past few decades because of its characteristics of soot free burning and higher efficiencies at less cost. The European Union decided to set 10% requirement of renewable energy in transport sector which is to be compiled with by 2020. In 2010, the transport sector utilized 4.70% of renewable energy out of which 91% was covered by biofuels. This paper discusses significance of methanol as a fuel for IC engines and its applicability in various sectors
