Motor sizing

1. Piston.

   dimension l=6cm =0.06m ,b=9cm=0.09m, h=9cm =0.09m V=lXbXh = 0.060.090.09 m^3 V1=486*10^(-6)m^3

2. Linkage

   v of linkage (1) V2 = 3cm20cm0.5cm = 3010^(-6)m(3)

   v= of linkage (2) V of linkage

V3 = 3cm*6cm*0.6
   = 14cm^3                   
   =14.4*10^(-6)m*(3)          

TOTAL VOLUME OF ARCYLIC IS = 44.4*10^(-6) m^(3) TOTAL VOLUME OF FOAM IS = 486*10^(-6) m^(3)

MASS

  Density of FOAM SHEET = 28 Kg/m^(3)
  Density of Acrylic sheet = 1180 Kg/m^(3)
  
   D=m/V
  
 1180 = m/44.4*10^(-6)
 
  m = 1180*44.4*10^(-6)
    = 52392*10^(-6)
   m1 = 0.052392 Kg

m2 = 2848610^(-6) = 13608 *10^(-6) kg

total mass (m) = m1+m2 = 52392*10^(-6) + 13608 10^(-6) = 6600010^(-6)kg =0.066kg

FORCE

  Co-efficient of friction between Acrylic sheet and Acrylic sheet is  0.6  

 F = nu*m*g
   = 0.6*0.066*9.8
   = 0.39N

TORQUE

 T=F*r
  =0.39*6.4
  =2.5 Ncm

safety factor is 1.5 T = 2.5*1.5 = 3.75 by comparing ~60 RPM

ADAPTER SIZING

sl.no	component name	current for 1	voltage	quantity	tot current
1	Arduino mega 2560	100mA	5v	1	100mA
2	IR Sensor	40mA	5v	2	80mA
3	Double channel relay module	80mA	5v	1	80mA
4	leds (red,green,yellow)	10 mA	5v	3	30mA
5	Dc motor	300mA	12v	1	300mA

safety factor is 1.2. 4 components are require 5 volts and total of current for all 4 components is 210mA multiplying by safety factor 1.2 210 mA*1.2 = 252mA.

1 component require 12v and current 100mA 100*1.2=120mA.

therefore one 5 volt 500mA adapter is required. one 12 volt 500mA adapter is required.
