Motor sizing and Adaptor selection

Adaptor selection :

                    Servo motor-650mA.
                    Factor of Safety=1.2.
                    Stall Current*Factor Of Safety=650*1.2=780mA<1A
                    Therefore,5V-1A adaptor is selected.

Motor selection :

                   length:l1=4cm,l2=5cm,l3=9cm
                   breadth
                   b1= b2=1.5cm
                   b3=4cm

                   thickness=t1=t2=0.4cm
                   t3= 0.5cm
                   Total Mass=M(1)+M(2)+M(3)
                             =V(1)*density + V(2)*density + V(3)*density
                             =l1*b*t*density+l2*b*t*density+l3*b*t*density
                             =(l1+l2)*b*t*density + (l3*b3*t3*density)

= (90.41.5 + 0.594)*1.18 Total Mass=27.612 g

                   W(G)=Weight of gum=15*9.8= 147g 
                   W(L)=Weight of links;
                   acceleration due to gravity(g)=9.8metre/(second)^2
                   W(L)=Total mass*g
                          =27.612*9.8
                          =270.5976 g
                   
                   Total weight=W(G)+W(L)
                           =270.5976+147
                           =417.5976

Torque = 417.5976* 4= 1.670kg/cm

Factor of Safety is 1.5.

=1.67×1.5=2.5kg/cm

Therefore, 60rpm is selected which provides 3.6kg/cm
