A thin rod with a mass of 3.49 kg and a length of 45.2 cm is free to rotate in the x−y plane and about the z axis, which passes through its center. Initially at rest, a constant torque, τ→ = (34.5 mN⋅m) k^, is applied through 5.48 s. thin rod, perpendicular to rotation axis through center I = 1 12 ML2
