Hi everyone!<br><br>Im developing an application with a physics library.<br><br>In the application I pre-setted some materials with the following properties,<br><br>Density, Friction and Restitution<br><br>Im not sure if this informations are truly trustable,<br><br>Can you guys just review this for me?<br><br>===|Wood|==<br>Density: 680 kg/m³<br>Friction: 0.4<br>Restitution: 0.7<br><br>===|Iron|==<br>Density: 7400 kg/m³<br>Friction: 1 (Steel = 0.8 )<br>Restitution: 0.85<br><br>===|Concrete|==<br>Density: 2300 kg/m³<br>Friction: 0.65<br>Restitution: 0.75<br><br>===|Rubber|==<br>Density: 920 kg/m³<br>Friction: 0.75<br>Restitution: 0.3<br><br>===|Polystyrene|==<br>Density: 80 kg/m³<br>Friction: 0.5<br>Restitution: 0.5<br><br>===|Plastic|==<br>Density: 1300 kg/m³<br>Friction: 0.35<br>Restitution: 0.6<br><br>References removed, this looks like spam mail.<br><br>Thanks!<p>Statistics: Posted by <a href="https://pybullet.org/Bullet/phpBB3/memberlist.php?mode=viewprofile&amp;u=9622">RicardoTk</a> — Fri Oct 19, 2012 5:24 pm</p><hr />
