here,
M3 = 0.215 g
M1= M2 = 100g
height of raingle = Sqr(b^2+p^2)
h = sqrt((10^2-12/2)^2 )
h = 8 cm
Point A :(6,8)
Point B :(0,0)
Point C :(12,0)
Centre of mass corrdiante for X :
Xcm = (6*100+0*100+12*0.215)/(0.215+2*100)
Xcm = 3.00 cm
Ycm = (8*100 + 0*100 + 0*0.215)/(0.215+2*100)
Ycm = 4.00 cm
Moment of inertia fo A :
Ia = M1*r^2
Ia = 2*100* 10^2
Ia = 20000 g.cm^2
Ia = 200000 Kg.m^2
Moment of Inertia for B and C :
Ib = mr^2
Ib = 200 * 8^2
Ib = 12800 g.cm^2
Ib = 128000 Kg.m^2
