11.3.81 Q22 In a certain four-engine vintage aircraft, now quite unreliable, each engine has a 12% chance of failure on any flight, as long as it is carrying its one-fourth share of the load. But if one engine fails, then the chance of failure increases to 24% for each of the other three engines. And if a second engine fails, each of the remaining two has a 36% chance of failure. Assuming that no two engines ever fail simultaneously, and...

QUESTION 1 metal part for which annual demand is 120,000 units is made on a CNC machine at a rate of 180 parts per hour. It can be made using tool steel costing $0.30 per pound or using brass stock costing $1.40 per pound. The weight per steel pi weight per brass piece is 0.0384 pounds. When it is made using steel it was found that 50% of the parts made per hour are defect-free; when it made using brass...

The pre-2017 Part 23 requirements of the Federal Aviation Regulations required that a single engine aircraft must stall at a maximum of 61 kt. Assume: maximum lift coefficient of 2.5 with flaps, standard day at sea level. Assume the wing is 100% efficient. (a) How big does the wing need to be for a 61 kt stall speed for an aircraft with a gross weight of 4,450 lb (in square feet)? 2. Assume that we plan to operate the airplane...
