**Text:**Each of the gears \( A \) and \( B \) has a mass of 10 kg and a radius of gyration of 190 mm, while gear \( C \) has a mass of 2.5 kg and a radius of gyration of 80 mm. Consider that a couple \( M \) of constant magnitude 10 N·m is applied to gear \( C \).**Diagram Explanation:**The diagram shows three gears labeled \( A \), \( B \), and \( C \). - Gears \( A \) and \( B \) each have a diameter of 250 mm. - Gear \( C \) has a smaller diameter of 100 mm and is positioned below and to the right of gears \( A \) and \( B \).- A couple \( M \) is applied to gear \( C \), indicated by an arrow and labeled "10 N·m."**Instructions:**Determine the number of revolutions of gear \( C \) required for its angular velocity to increase from 450 rpm to 1800 rpm. (You must provide an answer before moving on to the next part.)The number of revolutions of gear \( C \) required for its angular velocity to increase from 450 rpm to 1800 rpm is [_______] rev.
