Awave soldering machine failures follow 3-parameter weibull distribution with β = 1.6, η = 800 hours and γ = 500 hours. the cost of one pm is $ 6000 and the cost of an unexpected failure is $ 16 000. the machine operates 24 hours/day and pms are done every three months. determine the yearly cost for this maintenance schedule.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
