The Empire State Building in NYC is approximately 440 meters in height. The superstructure of the building is made of steel which means that energy will be transmitted through the buildings core at 1500 m/sec. If the building is being blasted and buffeted by a strong wind storm, at what frequency will the building sway in it's 1st mode of vibration. (Hint: think about what type of a resonator a building could be)

Finishing Operations

Finishing operations are the processes that are applied to the workpiece at the end of a manufacturing process, and after completing all other relevant operations that bring the product to its required dimensions. Finishing operations involve polishing, reducing the surface roughness, eliminating wrinkling, and grinding to enhance the surface texture and provide a better surface finish to the workpiece surface.
