MOTOR SIZING
- VOLUME OF MECHANISM
MAIN ROD L= 7.06cm , B=1.56cm , H=.5cm volume=5.5068 mm^3
SECONDARY ROD L=9.652cm , B=.43cm , H=.5cm volume=2.0752 cm^3
MAIN CIRCLE DIAMETER=12.7cm , thickness=.5cm 6.35 cm^3
TOTAL VOLUME=13.932 cm^3
density of acrylic sheet=1.18 gm/cm^3
MASS OF MECHANISM= 13.932 x 1.18= 16.4398 gm
- VOLUME OF MONSTER
L=3cm, H=6cm, B=4cm
Volume= LxBxH = 3x6x4 = 72 cm^3 VOLUME OF MONSTER:
Density of Plastic= 0.92 g/cm^3
mass = 72 x 0.92 = 66.24 g
- MASS OF COINS
mass of coins= 5g
- TOTAL MASS
Total mass = 16.4398 + 66.24 + 5 = 87.6798 gm = 0.08768 kg
5.Force involved is Vertical Force which is given by the formula
F = m x g F = 0.08768 x 9.8 F = 0.8593
6.Torque
T= F x r T= 0.8593 x 2.5 T= 2.15 BATTERY SIZING load current=250mA IR sensor load current=20mA Total current=270mA SOF1.2=324mA Therefore, Required adapter is 5v&0.5A
