The image you provided describes a bolted connection using A325X bolts, and it includes calculations for determining the capacity of the connection based on different assumptions. Here is a breakdown of what the problem involves:

1. Friction-Type Connection:

   • a. Based on shearing stress.
   • b. Based on gross area.
   • c. Based on net area.

2. Bearing-Type Connection:

   • a. Based on shearing stress.
   • b. Based on bearing of bolts.
   • c. Based on net area.

We are tasked with calculating the capacity under these different cases. To proceed with the calculations, we would need to use formulas related to each type of connection, considering the given values for the diameter of the bolts (19 mm), the diameter of the hole (22 mm), and the material properties such as yield strength (Fy = 248 MPa) and ultimate tensile strength (Fu = 400 MPa).

Do you want me to walk you through the solution step by step, or would you like to focus on a particular calculation (e.g., friction or bearing type)?
