### Bearing Stress and Shear Stress Calculation on a Supported BraceThis diagram represents a supported brace fixed by a bracket. The loading and geometric dimensions need to be analyzed to determine the bearing stress at Surface A and the shear stress developed in the seat of the bracket. Here is a breakdown of the elements in the diagram:#### Dimensional Details:1. **Bracket Dimensions:** - Thickness: 4 in - Width at Surface A: 8 in - Depth: 6 in - Distance from the base to the lower part of brace engagement: 3 in2. **Brace Dimensions:** - Thickness: 4 in - Length: 13 in (horizontal distance) - Effective length: 12 in - Vertical engagement depth: 5 in3. **Load Applied:** - Vertical force: 800 lb#### Mechanical Details:The forces and moments acting on the system need to be considered in order to calculate the stress distribution:1. **Bearing Stress at Surface A:** Bearing stress is the contact pressure between the surfaces. For surface A, the bearing stress can be computed by dividing the applied force (800 lb) by the contact area. - Contact area = width of Surface A * thickness of the brace. - Bearing stress \( \sigma_b \) can be calculated as: \[ \sigma_b = \frac{\text{Force}}{\text{Contact Area}} = \frac{800 \text{ lb}}{8 \text{ in} \times 4 \text{ in}} = \frac{800}{32} = 25 \text{ psi} \]2. **Shear Stress in the Seat of the Bracket:** The shear stress needs to be determined at the area where the bracket seat holds the brace. Assuming the bracket is experiencing shear over the width in contact with the brace, shear stress \( \tau \) is defined by the force divided by the shear area. - Shear area = Thickness of brace × Width holding the force (4 in * 4 in) - Shear stress \( \tau \) can be calculated as: \[ \tau = \frac{\text{Force}}{\text{Shear Area}} = \frac{800 \text{ lb}}{4 \text{ in} \times 4 \text{ in}} =
