Quarter-Car Suspension
This interactive simulator explores Quarter-Car Suspension in Classical Mechanics. ¼-vehicle vertical model: sprung vs unsprung masses, Kₛ, Cₛ, tire Kₜ, sinusoidal road — RK4 time histories. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Classical Mechanics.

How it works
Classic quarter-car vertical model: sprung mass (body), unsprung mass (wheel assembly), suspension spring-damper, and tire spring under a sinusoidal road profile. RK4 integration at 120 Hz.
Key equations
Mₛ zₛ″ = Kₛ(zᵤ−zₛ) + Cₛ(żᵤ−żₛ)
Mᵤ zᵤ″ = Kₜ(zᵣ−zᵤ) − Kₛ(zᵤ−zₛ) − Cₛ(żᵤ−żₛ)
