A rectangular steel alloy A-36 (structural steel) plate is hanging vertically and supporting a hanging weight of 90 kN. The plate has a length of 0.5 m, a width of 75 mm, and a thickness of 6 mm. Assuming that the bar deforms elastically under this loading condition and given the elastic properties for the steel: E = 207 GPa and u = 0.30

a.) What is the final length of the bar?

b.) What are the final dimensions (width and thickness) of the plate?

c.) What is the % reduction in area?

Fin efficiency is defined in relation to the maximum possible heat transfer rate from the fin for given convective conditions. This maximum possible heat transfer rate is defined on the basis that: The fin has a uniform temperature equal to that of its base The convection heat transfer coefficient is infinite The fin has zero thermal conductivity The fin has a uniform temperature equal to that of the surrounding air The fin is infinitely long
