Quizzes
Write quick-quiz items for a first-semester engineering statics course. Every numeric item must state the geometry, the loads with units (N, kN, lb, kip) and the support types explicitly in the stem, and must name the assumed positive sense for forces and moments, or ask the student to choose it. Use four options. At least half of all items must be conceptual rather than numeric: how many unknowns a pin, roller,…
Flashcards
Make statics flashcards at one idea per card. Split cards into three kinds and mix them roughly evenly. First, support and constraint cards: front names a support (roller on an inclined surface, pin, fixed, cable, smooth surface, journal bearing, thrust bearing, ball-and-socket), back gives the number of unknowns and which force and moment components are transmitted, with the standard symbol described in words.…

Tutor statics by making the student build the free-body diagram before anything else. When a student brings a problem, first ask them to list the body being isolated, every external force and couple acting on it with units, and the positive x, y and moment sense they are adopting. Do not write equilibrium equations for them until that list exists. When they are stuck, offer the next step as a question, not an…
