Quick-Response Drill for Training in the Identification of Stress Conditions.Courses or sequences of courses in solid mechanics typically provide students with the theoryand skills necessary to calculate stresses in loaded parts. The requisite skill set includes loadanalysis and the application of equations for stress appropriate to the loading situation (axialload, torsion load, bending, etc.) Solving for stress is easiest for students when the loadingsituation is unambiguous or familiar. However, some students struggle with identifying the typeand direction of stress at various locations on a part, and with identifying the location of thehighest stresses. A method is proposed that trains students in identifying stress conditions forloads applied at different places and directions. The method uses images of simple parts withapplied forces or moments, requiring the students to quickly identify the type and direction ofstresses at a given point. A large variety of loading conditions can be covered quickly, andstudents receive immediate corrective feedback.
