Questions
Effect of moment of inertia of a rigid body due to thermal expansion is where
detailed solution
Correct option is B
moment of inertia I=mK2 m is mass; K is radius of gyration on differentiating above equation and dividing same with above equation ∆II=2∆KK fractional change in moment of inertia is ∆II=2α∆t α is coefficient of linear expansion of solid ∆t is change in temperatureSimilar Questions
