As per your syllabus, eqn 6.34, the moment of inertia of a system of particles about an axis is which?
AI = Σ m_i r_i
BI = Σ m_i v_i²
CI = Σ m_i / r_i²
DI = Σ m_i r_i²
Answer & Solution
Correct answer: D. I = Σ m_i r_i²
syllabus eqn 6.34: I = Σ m_i r_i², where r_i is the perpendicular distance of mass m_i from the axis.
