Agim's Physics Playground — Kid-Friendly to Advanced STEM Wind Tunnel Lab

🎛️ Sandbox, Trebuchet & Wind

60 FPS • LIVE

👋 Touch or Hover Any Control Below!

🟢 What It Does: Every slider changes the invisible forces inside the Wind Tunnel in real time.

🟡 How To Understand It: Just like sticking your hand out a car window — faster wind pushes harder!

🏹 Hinged Trebuchet & Material Stress (MVP) σ = 60.2 MPa • Elastic

Beam Material (Young's Modulus E)

Counterweight Mass (m_cw) 90 kg

Sling Release Angle (θ_rel) 42°

Oak • COCKED (38 MPa) v₀ = 18.6 m/s • SF = 1.70x

38.3 MPa / 65 MPa (ELASTIC)

📐 Pen & Paper Force Triangle + Push/Pull/Twist |F_res| = 0.0 N

👉 Push / Pull Horizontal (F_push,x) 0 N

👆 Lift / Vertical Pull (F_pull,y) 0 N

🌀 Twist Force / Torque (τ) 0 N·m

🌱 Kindy Push/Pull: 0 N Push + 0 N Wind = 0 N

📐 Vector Triangle: ΣFx = 0 N, ΣFy = -44 N → |F_res| = 44.1 N ∠ -90.0°
