Interpretation:
The material used for the supporting structure of the statue of liberty is to be described in detail and the reasons for its heavy corrosion are to be mentioned.
Concept introduction:
A statue is built on a supporting framework to reinforce its strength.
Answer to Problem 95A
The supporting structure of the statue of liberty was made up of wrought iron and the reason for its corrosion was its seaside position which provided optimal conditions for the quick rusting of iron.
Explanation of Solution
Gustav Eiffel, the designer of the supporting structure of the statue of liberty, designed a skeletal frame for the statue which was 94 feet tall, made of puddled wrought iron whose main components were four compression posts. The skeleton supported a secondary frame which designed the outer curve of the statue. This frame was attached to the copper plates which formed the outer layer of the statue. The copper and iron parts were separated by a layer of asbestos to prevent galvanic corrosion between copper and iron. A smaller frame arose from the main support structure whose job was to support the head and the torch carrying arm of the statue. The mainframe was supported with diagonally aligned rods made up of wrought iron and was strong enough to stand erect in heavy winds. The iron parts were the ones that were more corroded as compared to copper due to the seaside facing and the saltwater.
The support structure of the Statue of liberty was made of wrought iron and corroded badly due to its seaside location.
