			<description>&lt;p&gt;New page: &lt;a href=&quot;/wikis/2009/bridgecoursemechanics/index.php/Image:3.9b.gif&quot; title=&quot;Image:3.9b.gif&quot;&gt;Image:3.9b.gif&lt;/a&gt;  Friction will &amp;quot;try&amp;quot; and prevent motion that is achieve equilibrium.   &amp;lt;math&amp;gt;\begin{align} &amp;amp; \text{For}\ \text{equilibrium}\ P-F=0 \\  &amp;amp; \text{that}\ \text{is}\ F=760\ \...&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;[[Image:3.9b.gif]]&lt;br /&gt;
&lt;br /&gt;
Friction will &amp;quot;try&amp;quot; and prevent motion that is achieve equilibrium.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&amp;amp; \text{For}\ \text{equilibrium}\ P-F=0 \\ &lt;br /&gt;
&amp;amp; \text{that}\ \text{is}\ F=760\ \text{N} \\ &lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
Also the maximum friction possible is &lt;br /&gt;
&amp;lt;math&amp;gt;\mu R=0.4\times 1960=784\ \text{N}&amp;lt;/math&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;F=760\ \text{N}&amp;lt;/math&amp;gt;&lt;br /&gt;
falls inside this maximum value and thus is the value of the friction.&lt;/div&gt;</description>
