Method: This is a research with a qualitative approach and an exploratory and descriptive nature, carried out in eleven undergraduate courses in Engineering at the Technology Center of the Federal University of Ceará. Semi-structured interviews were carried out and a focus group was constituted. The narratives were organized in knots and analyzed based on Bardin's discourse analysis. Results: 4 categories were formed from the ten nodes considered in the discourse analysis: Category 1: “grades”, “failure” and “stress”; Category 2: “teaching” and “relationship with teacher”; Category 3: “mental health”, “dropout”, “support” and “external support”; and Category 4: “being an engineering student”. Conclusion: It is necessary to propose preventive interventions, identification and care for the psychological distress of these students, in order to promote mental health and quality of life for students.

This study aimed to evaluate numerically displacements and tensions caused by tractor traffic on soil from the state of Ceará, Brazil. The rear tire weight (size 18.4-34 R1) on its contact area with the soil was 17.1 kN. Different inner pressures were considered in the numerical analysis based on the method of Finite Elements (96.5 kPa, 124.0 kPa, 151.0 kPa and 179.0 kPa), with their respective contact areas (0.2256 m2, 0 .1660 m2, 0.1522 m2 and 0.1393 m2). Our findings showed that vertical tensions on soil surface were nearly equal to tire inflation pressures. The lower pressure promoted less tension on the soil, showing that pressure reduction is necessary for further decreases on soil compaction up to a depth of 0.30 m. We also concluded that is essential to seek for solutions to reduce operating pressures, in order to decrease surface soil compaction derived from vertical and horizontal tensions.
