One of the National Academy of Engineering Grand Challenges for Engineering is Restore and Improve Urban Infrastructure. Infrastructure includes bridges and
roads, but it also includes water and sewer system, railroads, and power grids. In 2016, the state of Washington opened the SR 520 "floating" bridge. The bridge is
made of 77 floating concrete boxes anchored to the bed of the lake using 58 steel cables. Each cylindrical cable is 3 inches [in] thick, 1000 feet [ft] long, and made of
steel. Assume the specific gravity of steel is 7.9. What is the weight of one cable in units of pound-force [Ib]?

A legendary Dutch boy saved Holland by plugging a hole in a dike with his finger, which is 1.10 cm in diameter.
(a) If the hole was 1.80 m below the surface of the North Sea (density 1030 kg/m3), what was the force on his finger?
1.73
(b) If he pulled his finger out of the hole, how long would it take the released water to fill 1 acre of land to a depth of 1 ft assuming the hole remained constant in size? (A typical U.S. family of four uses 1 acre-foot of water, 1234 m3, in 1 year.)

At a depth of 10.9 km, the Challenger Deep in the Marianas Trench of the Pacific Ocean is the deepest site in any ocean. Yet, in 1960, Donald Walsh and Jacques Piccard reached the Challenger Deep in the bathyscaph Trieste. Assuming that seawater has a uniform density of 1024 kg/m3, approximate the hydrostatic pressure (in atmospheres) that the Trieste had to withstand. (Even a slight defect in the Trieste structure would have been disastrous.)

- Many of the cities in Holland are below sea level, and the sea is held back by a series of levies, called dikes. A story tells of a young Dutch boy named Hans Brinker, who was walking home along the dikes from school one day, and saw a small leak. He realized this was a real problem, so he stuck his thumb in the hole and cried for help. Imagine that the hole is 10.0 feet (3.08 meters) beneath the level of the sea beyond. How much pressure is being exerted at the hole? Hans’ thumb has a surface area of 0.895 square centimeters (Think: How many square centimeters in a square meter?). How much force does he feel on his thumb? Do you think that is a reasonable amount of force for a child to balance? Normally, to find the total pressure exerted, we’d have to add atmospheric pressure to the pressure exerted by the seawater. Why do we not have to worry about that here? *Problems involving the buoyant force are Newton’s Second Law problems, and should be solved with the same process!*arrow_forwardA legendary Dutch boy saved Holland by plugging a hole in a dike with his finger, which is 1.10 cm in diameter.
