QUestion: Please compute the bmep of an engine when the output is 450 hp, 2300 rpm, bore and stroke are each 5.5 in, and with 9 cylinders.   Please provide a complete solution. Thank you!

Pls Comment on the use of layout and other elements in the washing machine control panel. If errors occur based on this layout, walk through the accident scenario. Suggest potential ways of improving the interface to avoid a similar problem occurring.

Company Z has the following historical information about sales for one of its hydraulic pump models for the last 4 years: (PICTURE OF THE PERIOD AND YEARS) On the other hand, the manufacturing process used by Company Z is sequential* and has the following characteristics: (THE OTHER IMAGE) * Sequential; in the sense that the output of Mi is the input of Mi+1.** In any order; in the sense that they can be interchanged, e.g. MA -> MB or MB -> MA. The company's operating costs are as follows: Cost per final unit produced "defect free": $100 Cost per final unit produced "with defects": $150 Cost per excess inventory (units "free of defects"): $50 Cost per inventory shortage ("defect free" units): $200 Revenue per final "defect free" unit produced and sold: $250 We have the following operating conditions: - Any sequence of 3 machines can be used.- Only one machine can be used once, within the same sequence of machines.- You can work UP TO 720 hours per month.- A "level production"…
