A gear Box in a Baja SAE vehicle is required due to the objectives of the SAE competitions, which the vehicles are challenged to pass through different obstacles. A powertrain system has as the main objective the extension of the torque for the traction shaft of the vehicle, when compared to that one available in the engine. The Objective of this thesis is the description of a gear box project for a Baja SAE vehicle of the Piratas do Vale Team of Unesp Guaratinguetá. In the development of the thesis, a flowchart, developed by the team, was used, which includes a theory part and also the choice of shelf components. In this Project, the type of gearbox was chosen, besides the calculation of axles, gears, bearings and sealers, and software simulations were done for the critical parts. The transmission, developed in this thesis, is more complex than the current one used by the team, but the new one shows improvements, as a new reverse gear with high torque

This study aims to develop a computer program based on VBA programming language, using Microsoft Excel, for designing pumping systems of water. The program allows the user to determine the economical diameter, using the equation of Bresse, for a given installation, since the geometric elevation, the material of the tube, the accessories along the line and the volumetric flow are known. In addition, the program estimates the total annual cost of the installation for three different diameters, in order to compare which diameter is more advantageous from an economical perspective. The program interface is designed to be simple and intuitive with the intention of being didactic and offering to engineering students an advantageous tool to analyze this type of project. Microsoft Excel was chosen for this work because is present in virtually all personal computer, and is an indispensable tool for educational purposes

In this work, we discuss the procedures adopted for the design of built-up columns (laced and battened columns). Built-up columns are widely used in steel construction generally when the compression forces are relatively low and the column buckling lengths are large. They are commonly used in industrial buildings, for example, as posts for cladding, or as columns supporting a crane girder. Unlike columns with full section, in the case of built-up columns, it is necessary to evaluate the shear stiffness. In fact, the shear strength leads to a significant reduction of the critical load. In the context of this work, the components of the columns (chords, diagonals, posts, etc.) are formed by cold-formed members. In order to systematize and rationalize the verification of the built-up columns, this work aim to develop a computer program based on the standards NBR 14762, NBR 6355 and Eurocode 3, basically the considerations of the part EN 1993-1-1
