Question
In the figure shown what is ratio of reaction R1 to reaction R2?
Solution
Since, 
reaction is due to weight 5 kg
and
reaction is due to two weights 5 kg and 10 kg.
∴ ![<pre>uncaught exception: <b>mkdir(): Permission denied (errno: 2) in /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/util/sys/Store.class.php at line #56mkdir(): Permission denied</b><br /><br />in file: /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/util/sys/Store.class.php line 56<br />#0 [internal function]: _hx_error_handler(2, 'mkdir(): Permis...', '/home/config_ad...', 56, Array)

Thus, 
1:3 is the required ratio of the reaction R1 and R2.
