Question 3 A renewable energy company is designing a new wind turbine and needs to ensure the mechanical reliability of the blade mounting system. The blades are subjected to dynamic loads due to wind forces, and the mounting hub must withstand cyclic stresses without failure. You are tasked with analysing the design to ensure safety and longevity. a) List the key mechanical properties of materials that are critical for designing a wind turbine blade mounting system. [5 Marks] b) Explain how fatigue failure occurs in mechanical components and why it is a major concern for wind turbine blade mounts. [5 Marks]
