Question
This diagram is a detailed illustration of a gusset plate connection to a tension member using bolts. The primary focus is calculating the tension capacity of various lines through the plate. Below is a description and explanation of the components and steps involved:

### Components

- **Gusset Plate**: A structural component to connect beams and columns, shown here with dimensions of 12 inches in height.
  
- **Bolts**: The diagram specifies "10 – 7/8” Bolts" used to secure the connection.
  
- **Plate Thickness**: Labeled as \( t = \frac{1}{2}" \).

- **Tension Member**: Specified as an "A36 Steel Plate", which is subject to axial tension force denoted as \( P_u \).

### Dimensions and Lines

- **Bolt Placement**: Bolts are placed in a staggered pattern, with horizontal distances of 3 inches between them and vertical spacing of 2 inches between each bolt.

- **Lines of Consideration for Tension Capacity**:
  - **Line abcde (A_{n})**: A red dashed line following a staggered pattern around bolts.
  - **Line abfcgde (A_{n'})**: A black dashed line diverging from line 1, with extra bolting points considered.
  - **Line abfgde (A_{n''})**: Another staggered path considered for tension capacity.
  
- **Yielding Consideration**: Indicated as the evaluation of yielding over the \( A_{gross} \).

### Points and Areas

- **Points a, b, c, d, e, f, g**: Critical points on the plate where tension lines are considered.
  
- **Cross-sectional Areas**: 
  - \( A_n \) (net area) and \( A_g \) (gross area) are used to evaluate the tensile strength under different failure paths.

### Calculation Instructions

The tension capacity of the various lines through the plate is to be calculated as follows:
1. **Line abcde**: Analyze the net tensile area \( A_n \).
2. **Line abfcgde**: Consider additional bolt holes and evaluate \( A_{n'} \).
3. **Line abfgde**: Further evaluates net area with alternative bolt line \( A_{n''} \).
4. **Yielding**: Determine potential yielding using the gross sectional area \( A_{
