La rodadura permanente de un disco de radio &amp;lt;math&amp;gt;R&amp;lt;/math&amp;gt; sobre una superficie horizontal puede describirse mediante el campo de velocidades&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&amp;lt;math&amp;gt;\vec{v}^P = \vec{v}^O +\vec{\omega}\times\overrightarrow{OP}\qquad\vec{v}^O = v_0\vec{\imath}\qquad\vec{\omega}=-\frac{v_0}{R}\vec{k}&amp;lt;/math&amp;gt;&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
donde la superficie horizontal se encuentra en &amp;lt;math&amp;gt;y=-R&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
# Determine, para un instante dado, la velocidades de los puntos A, B, C y D situados en los cuatro cuadrantes del disco.&lt;br /&gt;
# Suponiendo &amp;lt;math&amp;gt;v_0=\mathrm{cte}\,&amp;lt;/math&amp;gt;, calcule la aceleración de dichos puntos para el mismo instante.&lt;br /&gt;
&lt;br /&gt;
==Velocidades==&lt;br /&gt;
Para cada uno de los puntos, basta aplicar la fórmula correspondiente&lt;br /&gt;
&lt;br /&gt;
;Punto A: Su vector de posición relativa es&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&amp;lt;math&amp;gt;\overrightarrow{OA}=-R\vec{\jmath}&amp;lt;/math&amp;gt;&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:por lo que su velocidad vale&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&amp;lt;math&amp;gt;\vec{v}^A = \vec{v}^O +\vec{\omega}\times\overrightarrow{OA}=v_0\vec{\imath}+\left|\begin{matrix}\vec{\imath} &amp;amp; \vec{\jmath} &amp;amp; \vec{k} \\ 0 &amp;amp; 0 &amp;amp; -v_0/R \\ 0 &amp;amp; -R &amp;amp; 0 \end{matrix}\right| = \vec{0}&amp;lt;/math&amp;gt;&amp;lt;/center&amp;gt;&lt;br /&gt;

;Punto C: &lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&amp;lt;math&amp;gt;\overrightarrow{OC}=R\vec{\jmath}&amp;lt;/math&amp;gt;{{qquad}}{{qquad}}&amp;lt;math&amp;gt;\vec{v}^C = \vec{v}^O +\vec{\omega}\times\overrightarrow{OC}=v_0\vec{\imath}+\left|\begin{matrix}\vec{\imath} &amp;amp; \vec{\jmath} &amp;amp; \vec{k} \\ 0 &amp;amp; 0 &amp;amp; -v_0/R \\ 0 &amp;amp; R &amp;amp; 0 \end{matrix}\right| = 2v_0\vec{\imath}&amp;lt;/math&amp;gt;&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
;Punto D:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&amp;lt;math&amp;gt;\overrightarrow{OB}=-R\vec{\imath}&amp;lt;/math&amp;gt;{{qquad}}{{qquad}}&amp;lt;math&amp;gt;\vec{v}^D = \vec{v}^O +\vec{\omega}\times\overrightarrow{OD}=v_0\vec{\imath}+\left|\begin{matrix}\vec{\imath} &amp;amp; \vec{\jmath} &amp;amp; \vec{k} \\ 0 &amp;amp; 0 &amp;amp; -v_0/R \\ -R &amp;amp; 0 &amp;amp; 0 \end{matrix}\right| = v_0(\vec{\imath}+\vec{\jmath})&amp;lt;/math&amp;gt;&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Obtenemos que el punto de contacto con el suelo posee velocidad instantánea nula, mientras que el punto superior posee velocidad doble a la de avance de la rueda. &lt;br /&gt;
&lt;br /&gt;
Las velocidades de los puntos O, B, C y D son perpendiculares al vector de posición relativo al punto A, como corresponde a que este se encuentre en el eje instantáneo de rotación:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&amp;lt;math&amp;gt;\vec{v}^P = \overbrace{\vec{v}^A}^{=\vec{0}} + \vec{\omega}\times\overrightarrow{AP}=\vec{\omega}\times\overrightarrow{AP}\perp\overrightarrow{AP}&amp;lt;/math&amp;gt;&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Aceleraciones==&lt;br /&gt;
La expresión general del campo de aceleraciones es&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&amp;lt;math&amp;gt;\vec{a}^P = \vec{a}^O + \vec{\alpha}\times\overrightarrow{OP}+\vec{\omega}\times(\vec{\omega}\times\overrightarrow{OP})&amp;lt;/math&amp;gt;&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
En este caso tenemos que la velocidad del punto O es constante, por lo que&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&amp;lt;math&amp;gt;\vec{a}^O = \frac{\mathrm{d}\vec{v}^O}{\mathrm{d}t} = \frac{\mathrm{d}v_0}{\mathrm{d}t}\vec{\imath}=\vec{0}&amp;lt;/math&amp;gt;&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
También es nula la aceleración angular&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&amp;lt;math&amp;gt;\vec{\alpha}=\frac{\mathrm{d}\vec{\omega}}{\mathrm{d}t}=\vec{0}&amp;lt;/math&amp;gt;&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
lo que nos deja con&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&amp;lt;math&amp;gt;\vec{a}^P = \vec{\omega}\times(\vec{\omega}\times\overrightarrow{OP})&amp;lt;/math&amp;gt;&amp;lt;/center&amp;gt;&lt;br /&gt;

&lt;br /&gt;
Desarrollando el [[Vectores_libres#Doble_producto_vectorial|doble producto vectorial]]&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&amp;lt;math&amp;gt;\vec{a}^P = (\vec{\omega}\cdot\overrightarrow{OP})\vec{\omega}-\omega^2\overrightarrow{OP}&amp;lt;/math&amp;gt;&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Para los cuatro puntos del enunciado, el vector de posición relativo al punto O está contenido en el plano OXY y es por tanto perpendicular a la velocidad angular, con lo que la aceleración de cada uno se reduce a&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&amp;lt;math&amp;gt;\vec{a}^P = -\omega^2\overrightarrow{OP}= -\frac{v_0^2}{R^2}\overrightarrow{OP}&amp;lt;/math&amp;gt;&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
En los cuatro casos resulta radial y hacia adentro del disco, lo que nos da las cuatro aceleraciones&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&amp;lt;math&amp;gt;\vec{a}^A = \frac{v_0^2}{R}\vec{\jmath}&amp;lt;/math&amp;gt;{{qquad}}{{qquad}}&amp;lt;math&amp;gt;\vec{a}^B = -\frac{v_0^2}{R}\vec{\imath}&amp;lt;/math&amp;gt;{{qquad}}{{qquad}}&amp;lt;math&amp;gt;\vec{a}^C = -\frac{v_0^2}{R}\vec{\jmath}&amp;lt;/math&amp;gt;{{qquad}}{{qquad}}&amp;lt;math&amp;gt;\vec{a}^D = \frac{v_0^2}{R}\vec{\imath}&amp;lt;/math&amp;gt;&amp;lt;/center&amp;gt;&lt;br /&gt;
