- LESSON 01Motion · Beginner
Projectile Motion
Understand: Resolve velocity into horizontal and vertical components.
Try: Change the launch angle and compare the maximum height and range with the same starting speed.
Self-check: Explain why mass does not change an ideal, drag-free trajectory.
Model boundary: The ideal model neglects air resistance, lift and wind.
- LESSON 02Oscillations · Beginner
Pendulum Dynamics
Understand: Distinguish the small-angle approximation from nonlinear oscillation.
Try: Increase the release angle and compare nonlinear and small-angle periods.
Self-check: Explain why an ideal pendulum's period depends on length but not mass.
Model boundary: Realistic mode adds approximate air drag and viscous bearing friction.
- LESSON 03Oscillations · Intermediate
Spring–Mass–Damper
Understand: Explore stiffness, mass, viscous damping and energy loss.
Try: Compare underdamped, critically damped and overdamped responses.
Self-check: Identify which terms remove mechanical energy in the selected model.
Model boundary: The friction mode regularizes dry friction; it does not calculate exact stiction.
- LESSON 04Structures · Intermediate
Truss Analysis
Understand: Use joint equilibrium to identify axial member forces.
Try: Change the rise-to-span ratio, then inspect the diagonal member forces and elastic extensions.
Self-check: Distinguish a compression force from a verified buckling capacity.
Model boundary: Only a three-member pin-jointed triangular truss is solved.
- LESSON 05Structures · Intermediate
Beam Analysis
Understand: Connect support reactions, shear, moment and deflection.
Try: Move the point load away from midspan and inspect local force and deflection.
Self-check: Explain why a nominal bending stress is not a certified safe load.
Model boundary: The beam uses linear elastic small-deflection theory and an assumed compatible cross-section.
