QuestionRotational mechanics / axis theorems
A planar, irregular shaped object has a mass of 2 kg. Its moment of inertia along the two orthogonal axes in the plane of the object are 3 kg m² and 4 kg m², respectively. The moment of inertia of the object along an axis perpendicular to the plane and passing through a point 0·5 m away from its centre of mass is represented by *I*. Which one among the following is the correct value of *I* ?
- (a) 7·5 kg m²
- (b) 7 kg m²
- (c) 5 kg m²
- (d) 1 kg m²
