Problem statement :  understand ...how a javalin can be thrown

                             ....trajectory ...of such a weapon
 
Opportunity :  A variable length (understand a telescope)

                       ...shaft or piston for a military tanker      

               ....ability to position the gun or launch shaft at a 'n' degree variable scale.

        
               ....thus ability to vary the range or achieve precision
                   for a target .
             
              
Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in 
      'http://uk.geocities.com/ravivenkatus/projects.pdf' ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
