At the beginning of each week, a machine is in one of four conditions: 1 = excellent; 2 = good; 3 = average; 4 = bad. The weekly revenue earned by a machine in state 1, 2, 3, or 4 is 100, 90, 50, or 10, respectively. After observing the condition of the machine at the beginning of the week, the company has the option, for a cost of 200, of instantaneously replacing the machine with an excellent machine. The quality of the machine deteriorates over time, as shown in the file P10 41.xlsx. Four maintenance policies are under consideration: Policy 1: Never replace a machine. Policy 2: Immediately replace a bad machine. Policy 3: Immediately replace a bad or average machine. Policy 4: Immediately replace a bad, average, or good machine. Simulate each of these policies for 50 weeks (using at least 250 iterations each) to determine the policy that maximizes expected weekly profit. Assume that the machine at the beginning of week 1 is excellent.
Calculate the biaxial stresses σ₁ and σ₂ for the biaxial stress case, where ε₁= 0.002 and ε₂ = - 0.001 are determined experimentally on an aluminum member of elastic constants, E = 71 GPa and v = 0.35 . Also, determine the value for the maximum shear stress.
In hydraulic fracture test, an induced fracture was created at 12.8 MPa. The fracture was reopened in three subsequent cycles. The reopening pressure at third cycle was found to be 6.4 MPa. If the tensile strength of rock is 6.3 MPa, and the pore water pressure is negligible. Determine the maximum and minimum principle stresses if the shut - in pressure was found to be 5.9 MPa

T = -25°C A 0.5 m × 1 m double paned window is made of two silica glass panes 1 cm thick, with air in between. Under steady conditions, linear (constant gradient) Outdoors temperature profiles are found in both silica panes, as well as the air. If the room (and the inner surface of h=18Wm²K the inner glass pane) is at a temperature of 25°C, while outdoors it is -25°C with a convection coefficient of 18 W m² K-1, what is the rate of heat loss through the window? What is the rate of heat loss if the room temperature is decreased to 20°C? Finally, what is the rate of heat loss for a room temperature of 25°C, but with one of the panes (and the air) removed? 1 cm 1 cm Room Temperature, 25° C or 20º C 0.5 mm Air, k=0.024 W m¹ K¹ Silica glass, k = 0.90 W m³ K

A well-known theoretician at Institution A is called by an experimentalist at Institution B to discuss what appears to be a new discovery, based on a highly original approach to the measurements in question. The discovery supports the theorists highly controversial approach to the problem. However there is a substantial amount of work needed before the results can be submitted for publication. The theorist has been invited to present a seminar at Institution C, where she is a candidate for a position, and where competitors of the experimentalist at Institution B are found. She was not told explicitly that his conversation with the experimentalist at Institution B was privileged.Questions What should she do in preparing for his visit? What are the potential conflicts of interests? What ethical considerations should the theorist consider in preparing her talk? Are there other actions that she could or should take in preparing for the visit? [OR]Suppose you have a strong interest in…
