📝 Problem

An object with moment of inertia I = 1.1 kg·m² rotates at ω = 20 rad/s. Find the rotational kinetic energy.

✨详细解答

1. Calculate Torque: Use the torque formula: τ = r × F (or τ = F · d).

1. Identify the applied force (F).

2. Identify the lever arm (d) from the axis of rotation to the line of action.

3. Calculate τ. For equilibrium, net torque is zero (Στ = 0).
