### Description:

A frame consists of members AB and BC pinned together with an internal pin at B. A and C are pinned external supports. Calculate the value of support reaction Ay to the nearest whole number. Enter positive for up, negative for down.

- **M (Moment) = 126 N·m**
- **P (Force) = 321 N**

#### Diagram Details:

- The frame forms an inverted "L" shape with a horizontal member AB and a vertical member BC.
- **Horizontal Member AB**:
  - Length: 4 meters (divided into two 2-meter segments)
  - An external clockwise moment \( M1 \) is applied at the midpoint of the horizontal segment.
  
- **Vertical Member BC**:
  - Total height: 3 meters (divided into two 1.5-meter segments)
  - A horizontal force \( P1 = 321 \, \text{N} \) is exerted to the right at the midpoint of the vertical segment.

#### Supports:

- Point A: Pinned support, allowing rotation but no translation.
- Point C: Pinned support at the base, allowing rotation but no translation.

### Calculation Requirement:

**Support Reaction Ay**: Determine the reaction at point A due to the given loads and moment. The result should be expressed as a whole number, positive for an upward reaction and negative for a downward one.
