1.	What is the formula for the moment of inertia? (m – a mass of the body, r – distance from the axis of the rotation)(a) ∑miri^2(b) ∑miri(c) ∑miri^4(d) ∑miri^3I have been asked this question during an interview for a job.I'm obligated to ask this question of Dynamics topic in division Dynamics of Electrical Drives of Electric Drives
Answer» Correct choice is (a) ∑miri^2 Easiest EXPLANATION: The moment of inertia is the property by the VIRTUE of which the BODY withstand the effect of angular acceleration. It DEPENDS on the shape and mass distribution of the body.
