10. A simply supported beam supports a triangular distributed load as shown. The peak load at the right end of the beam is \( 5 \mathrm{~N} / \mathrm{m} \). What is the bending moment at a point \( 7 \mathrm{~m} \) from the left end of the beam? IAl \( 15 \mathrm{~N} \cdot \mathrm{m} \) (8) \( 17 \mathrm{~N} \cdot \mathrm{m} \) (C) \( 28 \mathrm{~N} \cdot \mathrm{m} \) (D) \( 30 \mathrm{~N} \cdot \mathrm{m} \)
