e the axial stress of the aluminum rod in the figure if the temperature of the steel rod is y 30 degrees Celsius. Assume that the horizontal bar ABC is rigid. A Steel L = 0.9 m A = 300 mm² E = 200 x 10° N/m² a = 11.7 μm/(m-°C) B 0.6 m Aluminum L = 1.2 m A = 1200 mm² E = 70 x 10° N/m² a = 23 μm/(m-°C) 1.2 m с

2 To decrease the fuel consumption of large tankers, it is desirable to find hull shapes which minimize the drag force. The drag force F is a function of speed U, sizel, fluid properties p, µ and gravity g. Model ships 1/64 actual size are to be tested in a towing tank. Find the changes in the other parameters required to maintain dynamic similarity. Justify your answer by showing which dimensionless parameters you are keeping constant. Note: It is obvious that you cannot change the value of g. Find the force on the real ship in terms of the force on the model. Comment briefly on physical grounds why the parameter changes you found above might be difficult to achieve in practice.
