The ring gear \( A \) rotates clockwise with an angular velocity of \( \omega_{A}=20 \mathrm{rad} / \mathrm{s} \), while link \( B C \) rotates clockwise with an angular velocity of \( \omega_{\mathrm{BC}}=15 \mathrm{rad} / \mathrm{s} \). Determine the angular velocity of gear \( D \) measured clockwese. Express your answer using three significant figures. Enter positive value if the angular velocity is clockwise and negative value if the angular velocity is counterclockwise.
