This lesson explores what happens when ripple-induced transformation is contained within a system. Instead of dispersing, the change reflects, creating feedback loops that stabilize or intensify. This internal echo loop becomes a controllable force — one that maintains shape, resists collapse, or triggers self-sustaining dynamics.

🔹 Section 1: Concept

URFT sees force not just as interaction, but also self-reinforcement.

When ripple transformation is reflected inward by a system’s boundary (containment field), it recirculates.
This echo feedback can stabilize internal motion, amplify pressure, or even generate resistance.

This is how URFT explains:

Material rigidity
Pressure buildup
Dynamic equilibrium (e.g., floating, hovering, levitating)

Contained force is self-reinforced ripple transformation — a loop, not a one-off event.

🔹 Section 2: Analogy

Think of a drumhead struck at the center.

The initial pulse echoes out, hits the edge, then rebounds inward.
If the tension and material are right, it sets up a resonant standing wave — continuous motion inside a stable form.

That’s contained force:

Echoes locked in a loop, defining structure, pressure, and response.

🔹 Section 3: Simulation

Simulate a contained system:

Step 1: Ripple enters a closed boundary (e.g., ring or cavity).
Step 2: Ripple reflects and interferes with itself.
Step 3: Stable echo pattern forms — ripple doesn’t exit, it loops.

Compare to an open system where energy dissipates — no feedback, no force buildup.

Visual: One open, one closed structure showing ripple loop stability.

🔹 Section 4: Application

This explains:

How materials generate structural resistance
Why pressure builds in confined zones (e.g., vacuums, stars)
How active feedback loops could stabilize ripple-based propulsion or levitation

It also sets up ripple containment as the bridge to structural mechanics, replacing atomic bonds with echo lock-in.

🔹 Section 5: Definition

Contained Force: A self-sustaining transformation pattern formed when ripple-induced change is reflected within a system, creating feedback loops that stabilize pressure, shape, or resistance.

🔹 Section 6: Test Path

Design two systems:

One with closed boundaries (resonant cavity)
One with open escape paths

Apply identical ripple input:

Measure motion, containment, rebound, and long-term transformation
Confirm force feedback and stability emerge only in the closed system

Use this to simulate force retention without external constraints — echo defines the boundary.
