Mechanics of materials covers how solid bodies respond to load — stress, strain, deformation, and the point at which a member fails.
Each topic below has video walkthroughs, worked examples, and a quiz that regenerates its numbers every attempt.
Topics Covered
Pick a subtopic and start
Stress, Strain & Deformation
Axial loading, the stress-strain diagram, Young’s modulus, and elastic vs. plastic behaviour.
Shear & Moment Diagrams
Internal shear and bending moment along a beam, and the loading patterns that produce them.
Combined Stress & Mohr’s Circle
Principal stresses, maximum shear, and graphical stress transformation.
Column Analysis & Composite Sections
Buckling, slenderness, effective length, and transformed section properties.
Elastic & Plastic Deformation
The yield point, permanent deformation, and reading the stress-strain curve.
What Else the Exam Expects
Concepts that show up inside the topics above
Axial, Torsion & Bending
Axial loading, shear stress from twisting, and flexural stress in beams — the three load types most FE problems build on.
Deflection & Combined Loading
Beam deflection calculations, and analysing members carrying more than one load type at once, as most real structures do.
Quick Review with Shorts
Our YouTube Shorts cover single concepts — a formula, a sign convention, a common mistake — in about a minute.
A Note on Textbooks
A quality textbook alongside these resources makes a real difference. Mechanics of Materials by Barry J. Goodno and James M. Gere covers stress, strain, deformation, and structural behaviour with clear explanations and worked examples.
