&lt;p&gt;&lt;b&gt;Pàgina nova&lt;/b&gt;&lt;/p&gt;&lt;div&gt;[[Image:Rownia svg.png|thumb|right|250px|Pla inclinat i forces existents.]]&lt;br /&gt;
El &amp;#039;&amp;#039;&amp;#039;pla inclinat&amp;#039;&amp;#039;&amp;#039; és una superfície plana que forma un àngul agut en terra i s&amp;#039;utilisa per a elevar cossos a certa altura.&lt;br /&gt;
&lt;br /&gt;
Té la ventaja de necessitar-se una força menor que la que se gasta si alcem el dit cos verticalment, encara que a costa d&amp;#039;aumentar la distància recorreguda i véncer la força de roçament.&lt;br /&gt;
&lt;br /&gt;
Les lleis que rigen el comportament dels cossos en un pla inclinat foren enunciades per primera vegada pel gran matemàtic neerlandés [[Simon Stevin]], en la segona mitat del sigle XVI.&lt;br /&gt;
&lt;br /&gt;
;Eixemple&lt;br /&gt;
Imaginem que volem arrastrar el pes &amp;#039;&amp;#039;G&amp;#039;&amp;#039; des d&amp;#039;una altura 1 fins una altura 2; sent les posicions 1 i 2 a les que nos referim, les del [[centre de gravetat]] del bloc representat en la figura.&lt;br /&gt;
&lt;br /&gt;
El [[pes]] del bloc, que és una magnitut [[vector]]ial (vertical i cap avall), pot descompondre&amp;#039;s en dos components, &amp;#039;&amp;#039;F&amp;lt;sub&amp;gt;1&amp;lt;/sub&amp;gt;&amp;#039;&amp;#039; i &amp;#039;&amp;#039;F&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;&amp;#039;&amp;#039;, paralel i perpendicular al pla inclinat respectivament, sent:&lt;br /&gt;
&lt;br /&gt;
:&amp;#039;&amp;#039;F&amp;lt;sub&amp;gt;1&amp;lt;/sub&amp;gt;&amp;#039;&amp;#039; = &amp;#039;&amp;#039;G&amp;#039;&amp;#039; senet(a)&lt;br /&gt;
:&amp;#039;&amp;#039;F&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;&amp;#039;&amp;#039; = &amp;#039;&amp;#039;G&amp;#039;&amp;#039; cos(a)&lt;br /&gt;
&lt;br /&gt;
Ademés, la superfície del pla inclinat genera una força de roçament &amp;#039;&amp;#039;F&amp;lt;sub&amp;gt;R&amp;lt;/sub&amp;gt;&amp;#039;&amp;#039; que també haurem de véncer per a poder desplaçar-lo. Esta força és:&lt;br /&gt;
&lt;br /&gt;
:&amp;#039;&amp;#039;F&amp;lt;sub&amp;gt;R&amp;lt;/sub&amp;gt;&amp;#039;&amp;#039; = µ &amp;#039;&amp;#039;F&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;&amp;#039;&amp;#039; = µ &amp;#039;&amp;#039;G&amp;#039;&amp;#039; cos(a), sent µ el [[coeficient de roçament]].&lt;br /&gt;
&lt;br /&gt;
Analisant la figura, és evident que per a conseguir desplaçar el bloc, la força (&amp;#039;&amp;#039;F&amp;#039;&amp;#039;) que haurem d&amp;#039;aplicar, serà:&lt;br /&gt;
&lt;br /&gt;
:&amp;#039;&amp;#039;&amp;#039;&amp;#039;&amp;#039;F&amp;#039;&amp;#039;&amp;#039;&amp;#039;&amp;#039; = &amp;#039;&amp;#039;F&amp;lt;sub&amp;gt;1&amp;lt;/sub&amp;gt;&amp;#039;&amp;#039; + &amp;#039;&amp;#039;F&amp;lt;sub&amp;gt;R&amp;lt;/sub&amp;gt;&amp;#039;&amp;#039; = &amp;#039;&amp;#039;G&amp;#039;&amp;#039; senet(a) + µ &amp;#039;&amp;#039;G&amp;#039;&amp;#039; cos(a) = &amp;#039;&amp;#039;&amp;#039; G [senet(a) + µ cos(a)]&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
