**Problems 591**

**P12.10 to P12.14**. Using the Müller–Breslau principle, draw the influence lines for the reactions and internal forces noted below each structure.

**Diagram P12.10**
- A beam with three segments: AB, BC, and CD.
- Segment lengths: AB = 12', BC = 8', CD = 4'.
- Supports: A (fixed support), C (roller support), and D (free end).
- Notation for calculations: \( V_A, M_B, M_C, \) and \( R_C \).

**Diagram P12.11**
- A beam with three segments: AB, BC, and CD.
- Segment lengths: AB = 12', BC = 12', CD = 6'.
- Supports: A (fixed support), D (roller support), and C (with an internal hinge in segment BC).
- Notation for calculations: \( M_A, R_A, M_C, \) and \( V_C \) (to the left of support C).

**Diagram P12.12**
- A beam with four segments: AB, BC, CD, and DE.
- Segment lengths: AB = 12', BC = 18', CD = 18', DE = 12'.
- Supports: A (free end), B (roller support), D (roller support), and E (free end).
- Notation for calculations: \( R_B, V_B \) (to the left of support B), \( V_B \) (to the right of support B), \( M_C, \) and \( V_C \).

**Diagram P12.13**
- A beam with five segments: AB, BC, CD, DE, and EF.
- Segment lengths: AB = 20', BC = 8', CD = 10', DE = 10', EF = 10'.
- Includes a hinge at segment BC.
- Supports: A (fixed support), C (roller support), E (roller support), and F (free end).
- Notation for calculations: \( R_A, R_C, M_D, \) and \( V_D \).
