My Statics 1 & 2 Lifeline Notebook – The Only Thing That Got Me Through This Course! Hey there! I’m selling my personal Statics 1 & Statics 2 notes from the Mechanics, Structures, and Materials module in Year 1 of Mechanical Engineering — this was literally my lifeline throughout the semester. I compiled these notes from lectures, tutorials, and my own study sessions. Every page is packed with essential formulas, step-by-step methods, and clear summaries that helped me actually understand what was going on — not just memorize things for the exam. What’s Inside: Statics 1: Forces, Equilibrium & Free Body Diagrams (with clear examples!) Stress & Strain, Young’s Modulus, Poisson’s Ratio Truss Analysis (method of joints & sections) Beam Bending, Shear Force & Bending Moment Diagrams Shortcut methods for SF & BM using relationships
