A bridge on a small, rural road is designed to hold 10 cars when it is full and its maximum continuous weight that the bridge is designed to hold is 39,000 pounds. Assume that the average American car weighs 3750 pounds and that American cars' weights have a standard deviation of 200 pounds. If the bridge is fully loaded with 10 cars, what is the probability that it will be overloaded? Hint: Think about what the bridge designer thought the average weight of car that the bridge would hold would be and remember to draw a picture of the distribution to determine how you are treating the probability!

Do you think that the bridge in the previous question is safe to use? Why or why not?

When the federal government builds a project such as a dam, a road, or a bridge, it conducts a cost-benefit analysis in which the total costs of building the project are compared with the total benefits the project is supposed to bring. For example, in the aforementioned Tellico Dam, the costs of building the dam over the few years it took to build the dam and clear the land for the reservoir were approximately $100 million. The government (Tennessee Valley...

The cost of grading and spreading gravel on a short rural road is expected to be $300,000. The road will have to be maintained at a cost of $25,000 per year. Even though the new road is not very smooth, it allows access to an area that previously could only be reached with off-road vehicles. The improved accessibility has led to a 150% increase in the property values along the road. If the previous market value of a property was...

A rock is thrown upward from a bridge that is 31 feet above a road. The rock reaches its maximum height above the road 0.57 seconds after it is thrown and contacts the road 2.53 seconds after it was thrown. Write a function ff that determines the rock's height above the road (in feet) in terms of the number of seconds tt since the rock was thrown. f(t)=

A rock is thrown upward from a bridge that is 59 feet above a road. The rock reaches its maximum height above the road 0.9 seconds after it is thrown and contacts the road 2.4 seconds after it was thrown. Write a function f that determines the rock's height above the road (in feet) in terms of the number of seconds t since the rock was thrown. f(t)= Hint: the function f can be written in the form f(t)=c⋅(t−t1)(t−t2) for...

Imagine a tollbooth at a bridge. Cars passing by the booth are expected to pay a 50 cent toll. Mostly they do, but sometimes a car goes by without paying. The tollbooth keeps track of the number of cars that have gone by, and of the total amount of money collected. Model this tollbooth with a class called tollBooth. The two data items are a type unsigned int to hold the total number of cars, and a type double to...

. A prestressed road bridge of span 16 + 0.01 (35× 2) m consists of a concrete slab of 420 mm thick with parallel post-tensioned cables, in each of which the force at transfer is 440 kN. If the bridge is required to support a uniformly distributed applied load of 38 + 0.01 (135) kN/m , with tensile stress in the concrete not exceeding 0.85 N/mm2 at any time. Calculate the maximum horizontal spacing of the cables, their distance from...
