Chapter 20, Problem 1QAP

The steel frameword below is used to support the reinforced concrete slab used for an office area above the first storey.  The slab is 210 mm thick.  Sketch the loading that acts along members BE and FED.  Use a = 2.15 m and b = 5.25 m.  Refer to the 2024 OBC live load table.  The unit weight for the concrete is 24.15 kN/m3.find:Loading for member BE Loading for member FED Live and Dead Loads

Now unmount the filesystem. Create a sparse image file, called book.img, of the 2GiB hard drive. Use a hexdump program to look at book.img and work out the offsets that store the contents of the book youdownloaded. Record the offsets as a sequence of one or more ranges of hexadecimal numbers. For example, in the following hexdump the text The rain in Spain falls mainly on the plain. is stored at 0x10-0x1f, 0x30-0x4b (inclusive). 00000000: 0000 0000 0000 0000 0000 0000 0000 0000 .................00000010: 5468 6520 7261 696e 2069 6e20 5370 6169 The rain in Spai00000020: 0000 0000 0000 0000 0000 0000 0000 0000.................00000030: 6e20 6661 6c6c 7320 6d61 696e 6c79 206f n falls mainly 000000040: 6e20 7468 6520 706c 6169 6e2e 0000 0000 n the plain........ Compress the filesystem using gzip by running: #gzip book.img This should leave you with a file book.img.gz. You will use scp to transfer this file in a later task. Enter your ranges in answers2.json as the answer for question1. To…

We will consider a linear system and a nonlinear system under uncertainty, each expressed in the form of a set of stochastic differential equation (SDE) as follows: = da (Ax+ Bu)dt + Gdw, dx = f(x,u,t)dt+Gdw, (1) (2) where x is the state, u is the control, and dw is a differential increment of standard Brownian motion, i.e., E[dw] = 0 and E [dw(t)dw(t)] = dt-1. In this problem, we consider the linear SDE, Eq. (1), with a very simple model where x = R², u = [0,0] (no control), and dw R². The matrices A, B, and G are given as follows: A=02x2, B=02x2; G = [000] (3) where σp Є R represents the degree of the uncertainty, and let us take σ₁ = 2 and σ2 = 3. Assume that the initial state is deterministic and e(t = 0) = [0,0]. Take the following steps to simulate the given SDE for 1 € [0, 1]: (a): Consider the increments of w between each time interval [+1). Derive the analytical expression of Aw using w~N(02, 12), where Aw, w(tk+1) — w(tk). (c): Derive the approximate continuous-time EoM from…
