Q1: 3. An earth fill, when completed, will occupy a compacted volume of 187,000 cu yd. The borrow material which will be used to construct this fill is a stiff clay. In its bank condition,the borrow material has a weight of 114 lb/cu ft. The weight of this soil compacted is 129Ib/cu ft. Compute the required volume of the borrow material in BCY.See Answer
Q1: An airstream of speed 160 m/s and temperature 3000 K travels on the inside of a 30 cm I.D. steel tube whose wall thickness is 2.5 mm. On the outside of the tube, water coolant flows coaxially in an annular space 6.1 mm thick. The coolant velocity is 10 m/s, and it has a local temperature of 15°C. Both flows are approximately fully developed. The pressure of the airstream is around 140 kPa. Estimate the maximum wall temperature of the tube.See Answer
Q1: 7. Answer the following questions. [10 pt] ?. A solid sphere of mass 2 kg and radius 30 cm rolls down an incline without slipping. If the incline is 5 m high, how fast is the ball going at the bottom? b. A 500 g hoop with diameter 1.2 m is rolled down the same hill. If it too rolls without slipping, how fast is the hoop going at the bottom of the hill? c.Show that if the moment of inertia is given by I = CMR² , where c is a factor dependent on the shape of the object, that the acceleration down the incline is given by a=\left(\frac{1}{1+c}\right) g \sin \theta d. List two additional shapes with similarly formatted moments of inertia that could be rolled down the same hill. Rank all four (your two shapes, the sphere, and the hoop) in order of smallest to largest acceleration.See Answer

(5 point for free body diagram, 5 points for calculating reaction forces and moments if any, 5 points for Shear body diagram, 5 points for bending moment diagram)See Answer
Q1: The given: Project Description Beach Town is a coastal city on the west coast of Florida which is experiencing unprecedented growth because of recent investments in the area by various Fortune 500 companies and influx of people to the region. Historically Beach Town had a uniform mix of industrial, commercial, and residential community, and attracted tourists from various parts of the world because of its white sand beach. Recent investments in industrial and commercial sectors as well as large number of people settling in this area have created an explosive population growth, and the demand for freshwater has sky rocketed. A simplified map of Beach Town is attached. While the sketch is not drawn to scale, the relative positions of the various features of the city are depicted accurately. A river flows through the city and eventually flows in to the Gulf of Mexico. The base flow of the river (during winter) is approximately 500 cubic feet per second (CFS). There is a thriving community along the beach that caters to the tourists. During summer, the city receives approximately 1000 tourists per day which creates additional water demand. It is expected that number of tourists will increase by 10% each year for the next 20 years. Industrial establishments are located on the river upstream of the city. The establishments are grand fathered to discharge treated effluent in the river. Stormwater runoff from the manufacturing facilities drains in the river without much treatment. The industries on the river are permitted to withdraw freshwater from the river. A combined municipal/industrial landfill is located on the northwest boundary of the city that receives wastes from the community as well as from the industries. A freshwater lake is located within 4 miles of the city boundary and is relatively pristine. The city is also surrounded by high quality wetlands along both north and south boundaries. The overall population of the city is characterized as progressive and has active involvement in local decisions.See Answer
