Motor Sizing

Acrylic Link 1:

L=20 , H=1.7 , B=0.6

Volume= 20.4 cm^3
Density of Acrylic= 1.18 g/cm^3
Mass= 24.072 g

Acrylic Link 2:

L=7 , H=1.7 , B=0.6

Volume= 7.14 cm^3
Density of Acrylic= 1.18 g/cm^3
Mass= 8.4252 g

Foam Sheet:

L=7 , T=2.4 , B=7

Volume= 117.6 cm^3
Density of Foam sheet= 0.961 g/cm^3
Mass= 113.0136 g

Metal Sheets:

L=2 , B=2 , T=0.1

Volume= 0.4 cm^3 * 2
Density of Steel= 7.85 g/cm^3
Mass= 6.28 g

Total Mass= 151.7908 g = 0.15179 kg

Torque= Horizontal force * Radius

T= 0.90315 kg cm

Total Torque= Torque * FOS

Total Torque= 0.90315 * 1.5

Total Torque= 1.3547 kg cm

    This implies the required motor is 30 rpm DC Motor.

Servo motor to be used is tower pro SG-90
