प्रश्न
A torque of magnitude 400 Nm acting on a body of mass 40 kg produces an angular acceleration of 20 rad/s2. Calculate the moment of inertia of the body.
संख्यात्मक
उत्तर
Torque, τ = 400
Angular acceleration, α = 20 rad/s2
I = `τ/α`
= `400/20`
I = 20 kg/m2
∴ The moment of inertia of the body is 20 kg m2.
