![**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)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fffc9e826-c865-4bea-8e1f-6dcccd31bfb0%2Fbbcefd3d-7bf0-49da-b43d-7974cb481864%2Ftktsg_processed.png&w=3840&q=75)
