Project Status
    All Manufacturing completed : 
    
    Extension shaft
    
    
    -  Maximal strength/weight ratio obtained by maximizing the outer diameter.
    
 -  Hollowed socket further reduces mass.
    
 -  Steel pins used to transfer torque.    
    
 -  Strain rosettes applied at locations of maximal tensile stress.  Pins provide CSL.
    
 
    
    
    
    Hinge
    
    
    -  Sidewalls reduces stress on handle.
    
 -  Modeled as sets of rigid beams during analysis.
    
 -  Lots of extra material machined away.
    
 
    
    
    
    Handle
    
    
    -  Tapered design maximizes moment of inertia near hinge end, minimizes cross-sectional area near grip end.
    
 -  Flats milled to fit snugly in hinge contraption.
    
 -  INSTRON attachment machined directly into end, to maintain sturdiness
