Torque, angular momentum and a fixed axis-of-symmetry requirement

[QUOTE="rayoub, post: 6208426, member: 664567"] I'm reading through "University Physics 14th edition" by Young and Freeman. Section 10.5 on angular momentum for a rigid body around a fixed axis of rotation is derived as L = Iω. However, it shows that this is only the case for the fixed axis of rotation being an axis of symmetry. In section 10.2 on torque it is shown that torque for a rigid body around a fixed axis of rotation is τ = Iα. However, in this case, it doesn't mention the need for an axis of symmetry for this to be true. I'm wondering if it is just an omission or if there is a specific reason why there is no need for an axis of symmetry assumption in this situation. Thanks for any guidance. [/QUOTE]
