MOTOR SIZING

length(l)=10cm

breadth(b)=8cm

height(h)=5cm

radius of rod=0.5cm

Factor of safety(FOS)=1.5

density of foam board=0.8gm/cm^3

volume=(lbh) =10 *8 *5 =400cm^3

Volume=400cm^3

Mass=density * volume =0.8*400 =320gm

Mass(m)=320gm

Force=m g =3209.8 =3136

Force=3136N

Torque=force *radius =3136 *0.5 =1568N-cm

Torque=1568N-cm

Torque/9.8=160gm-cm

Total torque=torque FOS=1601.5=80gm-cm=0.8kg-cm

Total torque=0.8kg-cm

Motor selected is Tower Pro SG-90

**Adaptor selected is between the range of 3V-7.2V **
