V1=L * B * H= 15cm^3
Radius of circle (inside)=0.25cm
V2=pi * r * r=0.196375cm^3
Total volume of pushing plate =V1-V2 = 14.8036 cm^3
d=0.5g/cm^3
M=7.4018g
Supporting Guide
L=15cm ,B=2cm ,H=2cm
V1=60cm^2
Two supporting guides=> V2=2*60=120cm^3
Rectangular part : L=8cm ,B=0.5cm V2=4 cm^3
Circle:r=0.25cm V3=0.196375cm^3
Total volume of supporting guide = V1-V2-V3 = 115.80 cm^3
d=0.5g/cm^3
M=57.9g
Roller
Small cylinder
r=0.25cm , h=1cm
V1= pi * r * r * h= 0.196375cm^3
Two small cylinders => V1=2*0.196375=0.3925 cm^3
Big cylinder
r=0.75 , h=3cm
V2=pi * r * r * h = 5.3 cm^3
Total volume of Roller = V1+V2 = 5.6925 cm^3
d=1.5g/cm^3
M=8.5368g
Scissors
L=12cm, B= 1.5cm , W=0.5cm
Total 8 scissors
Volume = 8 * 12 * 1.5 * 0.5=72cm^3
d=1.18g/cm^3
M=84.96g
Nut
a=3.6cm
Volume= a^3 * srqt(2)/3- 3.142 * 0.25 * 0.25
Volume =21.9282-0.196375cm^3
Volume=21.731825 cm^3
d=7.85 g/cm^3
M=170 g
Lifting Table
Volume=Volume of side part *2 + Volume of back part+ Volume of down part
=2 * 15 * 10 * 0.42 + 10 * 10 * 0.42 + 15 *10 *0.42
=126+42+63 Total volume of Lifting table=231 cm^3
d=0.7g/cm^3
M=161.7g
Lead Screw
r=0.25cm , h=6cm
V=pi * r * r * h =1.1775 cm^3
Volume=1.1775 cm^3
d=7.85 g/cm^3
M=9.243g
Bolt
Volume= Volume of hexagon + volume of cylinder
=(3 * sqrt(3))/2 * a^2 * h +pi r * r h
=2.59 * 0.5 * 0.5 * 0.4+ 3.14 * 0.25 * 0.25 * 1
=0.2595+0.19625
Total volume of Bolt = 0.45575cm^3
d=7.85 g/cm^3
M=3.577g
TOTAL MASS=503.3186 g = 0.503 kg
Force=0.503 * 9.8
Force=4.9294 N
Torque=4.9294 * 7 =34.5058 N cm
Tmax= 34.5058 * Factor of safety
Tmax=51.7587 N cm = 5.28 kg cm
**This implies required motor is 30 rpm 12V Low Noise DC motor With Metal Gears-Grade A**
CONVEYOR SIDE PLATE
L=6cm B=5cm W=0.2cm V=15 cm^3 d=1.18g/cm^3 M=17.7g
CONVEYOR PLATE
L=19.5cm B=1.9cm W=0.4 cm V=14.82cm^3 d=1.18g/cm^3 M=37.17g
TOTAL MASS=54.87g=0.05487kg
FORCE=0.05487*9.8=0.5377N Torque=3.7640
Tmax= 34.5058 * Factor of safety
**Tmax=36.8872 Ncm = 3.7614 kg cm
This implies required motor is 60 rpm 12V Low Noise DC motor With Metal Gears-Grade A
Adapter Sizing
Operating voltage for DC motor = 12V
Current drawn by motor= 300mA
Factor of safety=1.2
Operating current= 1.2 * 300 =360mA
**The required adapter for DC motor is 1A, 12V Adapter**
