A steel strap is secured to a steel flange with a single steel pin as shown. The strap is 15 mm thick and is rectangular in section profile throughout. The pull on the strap is 125.0 kN. Shearing stress in the steel must not exceed 100 MPa. Tensile stress in the steel must not exceed 165.5 MPa.

(a) Determine the minimum diameter of the steel pin to the closest 2.0-mm increment (i.e., 20 mm, 22 mm, 24 mm, etc.) without exceeding the maximum specified shear stress.

(b) Determine the minimum width of the steel bar at cross section A-A without exceeding the maximum specified tensile stress.

(c) Using the diameter of the pin found in part (a), determine the minimum width of the steel bar at cross section B-B without exceeding the maximum specified tensile stress.
