A machine operates with a rotating mass that has a moment of inertia of 5 kg·m². If the mass is rotating at 10 rad/s, calculate the centrifugal force acting on the mass at a center distance of 0.2 m.
💡 Hint: Use the relationship of force with moment of inertia.
If a counterweight adds 3 kg to balance a 5 kg rotating mass offset by 0.1 m, determine the effectiveness coupled with another mass of 2 kg evaluated at 0.2 m offset.
💡 Hint: Think about the torque produced by the mass at its offset.
