Bolted Joint Design for Highway Cantilever Sign Panel Design Assignment 2 (covering chapter 8) A highway cantilever sign panel is mounted on a monapipe cantilever structure as shown in the figure. The structure must withstand wind loads, vibrations, and other environmental stresses while ensuring safety and reliability over its service life. Your task is to design the bolted joint connections between the two parts of the Monopipe cantilever structure, ensuring that the bolts and their dimensions meet safety standards and certification requirements. Given: * Wind speed: **150 km/h** (maximum gusts). * Temperature range: **-30°C to +50°C**. * Corrosion exposure due to salt spray from road de-icing. * Sign Panel Specifications: * Dimensions: 3.0 m x 1.5 m. * Weight of the panel: 80 kg. * Material: Aluminum alloy. * Monopipe Cantilever Structure: * Material: Steel (yield strength: 250 MPa, ultimate strength: 400 MPa). * Diameter of the monopipe: 200 mm. * Thickness: 10 mm. * Bolted Joint Parameters: * Type of bolts: Hexagonal head bolts (Grade 8.8) * Preload requirement: 70% of yield strength * Threads: ISO Metric Coarse Thread * Load Considerations: * Static load: Weight of the panel. * Dynamic load: Wind pressure on the panel. * Factor of Safety FoS=3.0. * additional details for calculations: * Drag coefficient $C_d$=1.2 * Air density $\rho$=1.225 kg/m$^3$. * Bolt thread pitch p=1.5 mm for M10 bolts. * Material modules of elasticity: $E_{st}$=200 GPa; $E_{Al}$=70 GPa. * Make the right assumption when needed Expected Deliverables 1. Static and dynamics Load analysis. 2. Calculations for preload and combined loading. 3. Bolt size and number selection to meet design requirements. 4. Recommendations for corrosion protection and maintenance. 5. Fatigue analysis (wind and vibration) for infinite life (Goodman and Soderberg criteria)

The following figure shows the PIV measurements of the pressure coefficient made in a wind tunnel at ten points along the upper and lower surfaces of an airfoil (angle of attack: 6°) 10 $C_p$ -10 -15 -20 -25 0 1 2 3 4 5 6 7 8 9 10 The pressure coefficient is defined as: $C_p = \frac{p - p_{\infty}}{\frac{1}{2} \rho_{\infty} V_{\infty}^2}$ On this formula, the subindices $\infty$ corresponds to the free flow coming from far away. A) Create an Excel file with the values of the pressure coefficient. Could you identify which values correspond to the upper surface and which values correspond to the lower surface? B) Demonstrate that $p = p_{\infty} + C_p \left(\frac{1}{2} \rho_{\infty} V_{\infty}^2\right)$ C) Calculate the values of pressure corresponding to the values of the pressure coefficient. Assume $p_{\infty} = 1010 \text{ hPa}$, $\rho_{\infty} = 1.2 \text{ kgm}^{-3}$, and $V_{\infty} = 10 \text{m/s}$ D) Calculate the average values of pressure for the two surfaces. E) Which surface gets the higher values of pressure? Sketch how the lift force takes place on the airfoil illustration.
