The figure below shows the cooling rate of steel cylinders subjected to a water quench and the hardenability curves based on the Jominy end-quench method for five different steel alloys. Using the data, fill in the blanks on the Final Exam Template with quantitatively correct hardness values for a 100 mm diameter cylindrical sample of 5140 steel subjected to a quench in water. Blank 1: The HRC value at the bar center. Blank 2: The HRC value at 1/2R. Blank 3: The HRC value at 3/4R. Blank 4: The HRC value at the bar Surface.

The US Transportation Security Administration (TSA) operates ten “checkpoints” for screening departing passengers at the Atlanta International Airport. Each checkpoint consists of a baggage conveyor belt, a CTX scanning/imaging machine, and a walk-through metal detector for passengers. However, not all ten checkpoints are necessarily operational all the time. This is because each checkpoint requires a team of three TSA employees to staff it, and there is not always a need to have ten checkpoints running simultaneously. Passengers arriving at the airport are first greeted by a “greeter” who directs each passenger to a specific checkpoint in operation. Once “greeted,” each passenger joins the single line at their assigned checkpoint for screening, and it takes an average of 2 minutes to process each passenger. The greeter’s job is to evenly divide arriving passengers between the checkpoints in operation, although the rate at which passengers arrive at the airport and approach the greeter varies with the time of day. Currently, the number of checkpoints that the TSA operates during the 8:00 a.m. to 4:00 p.m. time intervals of the day is described in the table below. (Do not round intermediate calculations. Round your answers to four decimal places.)                        Period                         Average Number of Passengers Arriving per Hour                 Number of Checkpoints        8:00 AM to 4:00 PM                                                    200                                                                             10                     What is the average time (minutes) a passenger spends in line waiting for service at each checkpoint?

Grand Forks Fish Market buys fresh Boston bluefish daily for $20.00 per pound and sells it for $30.00 per pound. At the end of each business day, any remaining bluefish is sold to a producer of cat food for $ 5 per pound. Daily demand can be a normal distribution with a mean of 2000 pounds and a standard deviation of 1000 pounds. Use the table below for Z-value.  What is the optimal stocking level?                                Service Level             Z-Value                                    0.3333                   – 0.432                                    0.4                          – 0.253                                    0.5                                 0                                    0.6667                     0.432
