The distance to mass mi is du = 27 cm and the distance to mass mz is ds = 45 cm. The distances are measured from the axis O. What is the combined moment of inertial for the three point objects about the axis o? d. d. I= kg.m Incorrect con about us help career mo playboy

Answer 1

given

m1 = 2.6 kg

m2 = 3.8 kg

m3 = 3.3 kg

d1 = 0.27 m

d3 = 0.45 m

from the realtion

moment inertia of a particle I = md^2

total moment on inertia of the three particle system

I = m1d1^2+m2(0)^2+m3*d3^2

I = 2.6*0.27^2+3.3*0.45^2 = 0.189+0.668

I = 0.857 kg m^2
