To this end, descriptive and applied research was used as a data collection method, through the theoretical foundation and analysis of the main variables existing in the teaching and learning process. With the qualitative and quantitative analysis of the data collected, it was found that difficulties with the large volume of content presented during the course, together with problems in choosing the best study strategy, directly affected the student's performance. Deficiencies found in the establishment of basic subjects, seen during High School, also constituted obstacles in teaching. Added to these points were problems with social and interpersonal relationships. Finally, through the case study carried out with the application of questionnaires, it was possible to verify that the scenario in which the student found himself when entering college was a challenge, requiring him to recycle his old knowledge and establish plans to acquire new ones.

Among the main difficulties associated with computational modeling from the FEM, there is the determination of the loads to be applied in the developed structural models, when these are most requested from the interaction between the vehicle and the road. The present work focused on the structural analysis of the roll cage of a Baja SAE from the construction of a dynamic multibody model of the SB-20 - prototype of the “Siará Baja” local extension project - of the four-post track simulator type, mitigating the difficulty associated with the quantification of loads, from the perspective of the vehicle as a system excited by the base. The materials and methods used for the structural analysis include the construction of the excitation functions of the system - taken from the synthesis of the vehicle operating profile -, the construction of the mechanical model of finite elements - from the stages of general conception, preparation of geometry, elasto-plastic model, mass distribution and general description - modal analysis, transient structural analysis, dynamic system response analysis and static and fatigue failure analysis. From the elaborated, results were obtained for the transmissibility of displacement, acceleration of the sprung mass in function of the driver comfort, safety factors for static failure and time of operation of the vehicle until fatigue failure. In conclusion, the computational modeling strategies used for the construction of the mechanical model proved to be effective, the model developed showed satisfactory mechanical behavior and the roll cage, component of analysis, obtained results compatible with the operation requirements, with static failure being its critical failure mode.

Specially the the brake sistem, that has the extremly important task of deccelerating the vehicle in a safe and eficiente way, despite the surrounding conditions. Thus, this work will approach a design methodology of a Baja SAE brake sistem, wich is a Vehicle built by college students from many universities who have in mind a competition, on wich the designs will be judged and ranked. For such vehicles, beyond the driver´s and vehicle’s structure safety, there is one more concerning in the case the brake sistem doesn’t work correctly, this concerning is the disqualification of the team from the competition. To build a solid and reliable methodology, in this job i will talk about the differents kinds of brake sistems availables on the market and their basic components, also was made a recomendation about the best combination of triggering method and the triggered assembly, so, this methodology was built considering a hydraulic system with disc-calliper assembly at the wheels. At first, the vehicle behavior during the braking was explained by doing an analisys of the longitudinal vehicle dynamics, further was shown how to calculate the braking power of the system by calculating the braking torque and braking forces that it is able to generate. This writing was built for the engeneering students, specially the ones who participate on a Baja team and are responsibles by the brake design of it’s team, and with a main goal to enlight and provide a guide on how to choose your componentes and design your system. When puted to test at the regional competition SAE Northeast 2020, the showed methodology came out to be satisfactory by receiving the third place on the design presentation.

To optimize this process, large companies often employ integrated or outsourced systems to carry out this crucial task. However, not all companies can afford the licensing costs associated with these mentioned software solutions, so alternative options must be considered. With the growth of technology and automation, low-code development tools that require minimal or no coding are becoming increasingly popular due to their practicality and efficiency compared to traditional development methods.Therefore, this work will introduce a “no-code” development technology called “Bubble”, and an application will be developed for the collection, standardization, and organization of these maintenance records, which will later be used to create indicators to assist in the company's maintenance planning. The system was implemented in a textile industry within the spinning sector, specifically for a type of machine called “Open End” used for spinning elements. Finally, the system yielded positive outcomes concerning cost reduction and potential for delivering indicator results.
