Question

A large flat barge is used during the construction of a river crossing. It has a plan area of 10
metres by 20 metres and vertical sides so that it resembles a simple rectangular prism. In
fresh water it draws 620 mm when there is nothing positioned on the barge. The draft in
seawater (RD 1.025) when the barge has been loaded is 942

A large flat barge is used during the construction of a river crossing. It has a plan area of 10 metres by 20 metres and vertical sides so that it resembles a simple rectangular prism. In fresh water it draws 620 mm when there is nothing positioned on the barge. The draft in seawater (RD 1.025) when the barge has been loaded is 900+ x mm where x- last 2 digits of your student number, Calculate the mass of construction equipment and materials on the barge. Clearly state the last 2 digits used from your student number in your assignment submission

Answer 1

The question provides criteria in two different situations, and it is required to find the weight of construction materials and equipments in Barge.

The problem is approached through Archimedes principle which states that weight of water displaced equals weight of material immersed. The first criteria is used to calculate the weight of barge in fresh water. Second criteria is used to calculate total weight in seawater. The difference of two value is calculated to determine the weight of materials and equipments.
