A tie consists of 2 ISA 7.5 × 7.5 × 0.8 cm placed back to back with a...
(i) When tacking rivets are not provided, d = 18 + 1.5 = 19.5
Single angle strength
A1 = 8(75 - 19.5 - 4) = 412 mm2
A2 = 8(75 - 8/2) = 568 mm2
Anet = 412 + 568 × 0.685 = 801.16 mm2
Strength = 801.16 × 150 = 120174 N
Strength of 2 ISA = 2 × 120.17 = 240.35 kN
(ii) When tacking rivets are provided
Anet = 2(Ag - deduction for hole) = 2(1138 - 19.5 × 8) = 1964 mm2
Strength of 2 ISA = 1964 × 150 = 294.60 kN.

To determine the safe pull for the given tie, we need to consider the strength of the rivets and the stress on the tie.
1. Calculation of Safe Pull without Tacking Rivets:
To calculate the safe pull without tacking rivets, we need to consider the area of the rivets and the stress on the tie.
- Area of one rivet (A_r): The area of a circle is calculated using the formula A = πr^2, where r is the radius. In this case, the diameter of the rivets is given as 1.8 cm, so the radius (r) is 0.9 cm or 0.009 m. Thus, the area of one rivet is A_r = π(0.009)^2 = 0.00025447 m^2.
- Area of one tie (A_t): The tie consists of two ISA sections placed back to back with a gusset plate between them. The total area of one tie is the sum of the areas of the two ISA sections and the gusset plate. The area of one ISA section is given as 7.5 cm × 7.5 cm = 0.05625 m^2, and the area of the gusset plate is 0.8 cm × 0.8 cm = 0.0064 m^2. Therefore, the total area of one tie is A_t = 2(0.05625) + 0.0064 = 0.1189 m^2.
- Stress on the tie (σ_t): The axial tension stress is given as 150 MPa, which is equal to 150 N/mm^2 or 150 MN/m^2. Therefore, σ_t = 150 MN/m^2.
- Safe pull without tacking rivets (P): The safe pull is calculated by multiplying the area of one rivet with the stress on the tie. P = A_r × σ_t = 0.00025447 × 150 MN/m^2 = 0.03817105 MN = 38.171 kN.
2. Calculation of Pull with Tacking Rivets:
When tacking rivets are provided, we need to consider the additional strength from the tacking rivets.
- Number of tacking rivets: The number of tacking rivets is not mentioned in the question, so we'll assume it to be four, one on each corner.
- Additional area from tacking rivets (A_tacking): The area of one tacking rivet is calculated using the same formula as before. A_tacking = π(0.009)^2 = 0.00025447 m^2. Therefore, the additional area from all four tacking rivets is A_tacking_total = 4 × 0.00025447 = 0.00101788 m^2.
- Total area of one tie with tacking rivets (A_t_total): The total area of one tie with tacking rivets is the sum of the areas of one tie and the additional area from tacking rivets. A_t_total = A_t + A_tacking_total = 0.1189 + 0.00101788 = 0.11991788 m^2.
- Pull with tacking rivets (P_total): The pull with tacking rivets is calculated by multiplying the

The total area of one tie is the sum of the areas of the two ISA sections and the gusset plate. The area of one ISA section is given as 7.5 cm × 7.5 cm = 0.05625 m^2, and the area of the gusset plate is 0.8 cm × 0.8 cm = 0.0064 m^2.

- Total area of one tie with tacking rivets (A_t_total): The total area of one tie with tacking rivets is the sum of the areas of one tie and the additional area from tacking rivets. A_t_total = A_t + A_tacking_total = 0.1189 + 0.00101788 = 0.11991788 m^2.
- Pull with tacking rivets (P_total): The pull with tacking rivets is calculated by multiplying the
