8. (a) Solve the initial-value problem dt and show that sint, n even L 0, n odd in the interval n <K(n +1)T. (b) Solve the initial-value problem dt and show that y()=(n+1) sint in the interval 2nπ〈t〈2(n+1)T. This example indicates why soldiers are instructed to break cadence when marching across a bridge. To wit, if the...

In 1831, soldiers marched across the Broughton Bridge in England in "lock step"-that is, marching in time together. As they marched, the bridge began to bounce in time with their footsteps; the amplitude of this bouncing became larger and larger until the bridge suddenly collapsed. Part A Explain why the lock step of the soldiers caused this collapse and why afterward soldiers were ordered to "break step," or march at their own individual rates, as they crossed bridges. Match the...
A toll bridge across the Mississippi River is being considered as a replacement for the current 1-40 bridge linking Tennessee to Arkansas
A toll bridge across the Mississippi River is being considered as a replacement for the current 1-40 bridge linking Tennessee to Arkansas. Because this bridge, if approved, will become a part of the U.S. Interstate Highway system, the B-C ratio method must be applied in the evaluation. Investment costs of the structure are estimated to be $17,200,000, and $332,000 per year in operating and maintenance costs are anticipated. In addition, the bridge must be resurfaced every fourth year of its...

Exercise 2. (20 points.] The Lorentz Attractor is a well-known example of a chaotic sys- tem, i.e. a system that can have radically different responses for arbitrarily close initial conditions. Its dynamic equations are = a(32-2) 22 = 26-23) - 12 which can be used to model a two-dimensional flow of liquid warmed from below and cooled from above. To study the system behavior, perform the following: a) Create the MATLAB function dx-Lorentz(x, a, b, c) to compute the derivative...

Designing a truss bridge This lab involves the design of a truss bridge, which is a Pratt truss and should be designed to handle the loads shown in Fig- ure l (1 kip = 1000 lb). Note that the loads are the same on each of the two trusses for the bridge, so what is in Figure 1 is only half the loading on the bridge. Your job is to develop an optimal design for the bridge, Figure 1. Schematic...

Write the function below in scheme/lisp programming language. Drracket Exercise: It is well known that n^2 is equal to the sum of the first n odd numbers. For example, 16 = 4^2 = 7 + 5 + 3 + 1. Write a function that takes as input a natural number, n, and that returns the square of its input by adding the first n odd numbers. Your code may not contain delayed operations and must use accumulative recursion.
