Question
**Archery Mechanics: Analyzing Forces in the Bow** An archer aiming at a target is pulling with a 64-lb force on the bowstring. **Diagram Explanation:** The diagram shows an archer standing and holding a bow. The bow is drawn with a force of 64 lbs. The diagram includes measurements that relate to the positions and forces involved in the action: - **A** is the point where the archer holds the bowstring. - **B** is directly above A, 8 inches up. - **C** is 24 inches to the right of A, at the midpoint of the bowstring. - **D** is directly below point C, 32 inches down. - Points **J** represents a point along the bow where internal forces will be analyzed, 16 inches above and below point C. Assuming that the shape of the bow can be approximated by a parabola, determine the internal forces at point J. 1. **Axial Force \( F \)** at point J: (Enter value and angle) 2. **Shear Force \( V \)** at point J: (Enter value and angle) 3. **Bending Moment \( M \)** at point J: (Enter value and angle)
