Question 5 (20 points) You want to create a virtual hot-rolled coil (HRC) steel mill with a capacity of 1,000 tons/month using the futures market to benefit from the spread between the inputs and the output. Assume your costs are: 2 tons of iron ore and 1 ton of coking coal ton of steel and your output is hot-rolled coil steel. Future contracts are available on hot-rolled steel, iron ore, and coking coal. You are bullish that from T-O to...

Analysis of a random sample consisting of m= 20 specimens of cold-rolled steel to determine yield strengths resulted in a sample average strength 29.8 ksi. A second random sample of n =25 two-sided galvanized steel specimens gave a sample average strength of 34.7 ksi. Assuming that the two yield-strength distributions are normal with true standard deviations 4.0 and 5.0. We wish to test if the difference in the true average strengths for cold rolled steel and galvanized steel is less...

P6.074 The torsional assembly consists of a cold-rolled stainless steel tube connected to a solid cold-rolled brass segment at flange C. The assembly is securely fastened to rigid supports at A and D Stainless steel tubes (1) and (2) have an outside diameter of 3.125 in, a wall thickness of 0.082 in., a shear modulus of G = 14200 ksi, and an allowable shear stress of 38 ksi. The solid brass segment (3) has a diameter of 1.3125 in., a...

During the construction of the LRT railroad track, hot rolled structural steel A36 of 10-m-long rails were used. The steel rails were laid on the track with a 5-mm gaps between the rails during the night when the temperature of the steel was 20°C. Determine the normal stress in the steel rails when the temperature of the steel is 40°C. E = 200 GPa and a = 11.7 x 10-6 m/(m °C)

A hot bath at T = 92.2 °C is connected to a cold bath at T = 15.6 °C by an insulated metal rod as shown in the diagram (Figure 1). The metal rod is made from two metals, aluminium is next to the hot bath and has a length li = 50.5 cm, steel makes up the remainder of the rod. The junction between the aluminium and steel has a temperature T; = 40.2 °C. The rate of energy...
