<h2 style="color:#2a5db0;">Body Roll (Limbung) & FULL Simulator Dashboard + Real-Time Graph (EEC / EU Type Approval)</h2>
<p>
Body roll adalah efek samping dinamika kendaraan. EEC menilai stabilitas kendaraan melalui:
<ul>
<li>Yaw stability</li>
<li>Lateral acceleration</li>
<li>Roll motion</li>
<li>Lateral displacement</li>
</ul>
</p>
<hr />
<h3 style="color:#2a5db0;">1. Lateral Acceleration & Roll Moment</h3>
<p>
<b>Lateral Acceleration (a<sub>y</sub>):</b> a<sub>y</sub> = v² / R<br>
<b>Roll Moment (M<sub>roll</sub>):</b> M<sub>roll</sub> = m × a<sub>y</sub> × h
</p>
<hr />
<h3 style="color:#2a5db0;">2. Roll Motion & Yaw Stability</h3>
<ul>
<li>Roll angle & roll rate menentukan seberapa cepat kendaraan miring.</li>
<li>Yaw moment menentukan arah kendaraan saat lateral force berubah.</li>
<li>Oversteer / Understeer terjadi jika roll motion tidak terkendali.</li>
</ul>
<hr />
<h3 style="color:#2a5db0;">3. Lateral Displacement</h3>
<p>
Perpindahan lateral = hasil interaksi gaya lateral, roll moment, & yaw moment. Limbung berlebihan → kendaraan keluar jalur.
</p>
