			<description>&lt;p&gt;New page: Vertically the forces on the tank are in equilibrium  &amp;lt;math&amp;gt;\begin{align} &amp;amp; \uparrow \ R-mg=0 \\  &amp;amp; R=800\times 9\textrm{.}8=7840\ \text{N} \\  \end{align}&amp;lt;/math&amp;gt;  The maximum friction is ...&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Vertically the forces on the tank are in equilibrium&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&amp;amp; \uparrow \ R-mg=0 \\ &lt;br /&gt;
&amp;amp; R=800\times 9\textrm{.}8=7840\ \text{N} \\ &lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The maximum friction is thus,&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;F=\mu R=0\textrm{.}6\times 7840=4704\ \text{N}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This is less than the force exerted by the rope. Thus resultant horisontal force is&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\leftarrow \ 5000-4704=296\ \text{N}&amp;lt;/math&amp;gt;&lt;/div&gt;</description>
