Items are inspected for flaws by two quality inspectors. If a flaw is present, it will be detected by the first inspector with probability 0.9, and by the second inspector with probability 0.7. Assume the inspectors function independently.
a. If an item has a flaw, what is the probability that it will be found by both inspectors?
b. If an item has a flaw, what is the probability that is will be found by at least one of the two inspectors?
c. Assume that the second inspector examines only those items that have been passed by the first inspector. If an item has a flaw, what is the probability that the second inspector will find it
The object ABC consists of two slender rods welded together at point B. Rod AB has a mass of 1 kg and bar BC has a mass of 2 kg. Knowing the magnitude of the angular velocity of ABC is 10 rad/s when thetha is zero.
A large drainage channel has a trapezoidal cross section with a bottom width of 75 feet and bank side slopes of 4:1 (H:V). If the normal depth of flow is 25 feet, compute the normal flow rate through the channel (Q in cfs).
A 75g , 30cm--long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 12g ball of clay traveling horizontally at 2.5m/s hits and sticks to the very bottom tip of the rod.
Your engineering consulting firm has been asked to determine the specific weight of an unknown material. You decide to use the concept of buoyancy to figure this out. So you weigh the material in both air and water.
