For the following G(s), find analytical expressions for the magnitude and phase response. G(s)=\frac{10}{s(s+1)}

[10] 1. Design a spiral column cross section to support Pu 500 kips and Mu= 200 ft-kip. The column is in a braced frame and has an unsupported length of 9 ft. f'c= 4,000 psi and f y = 60 ksi. Assume that the column is pin-fixed and M1 / M2 = +0.7. The column is not exposed to the environment. The maximum nd, f,0.45D f (A, / A.)–center-to-center spacing of the spirals is s < \frac{\pi d^2spfy}{0.45DCFc\mleft\lbrack\mleft(\frac{Ag}{ac}\mright)-1\mright\rbrack} where dsp = diameter of spiral, Dc = diameter of core (outside to outside of spirals), Ag= gross area, and Ac =area of core. Hint: for a spiral column, based on Cl. 10.3.6.1 of ACI-318. A_{g(\text {trial})}=\frac{P_{u}}{0.55\left(f_{c}^{\prime}+f_{y} \rho_{t}\right.}

Produce a multi-view drawing of the given object using 3d angle projection for manual drawing on A2-sized paper. Use view B as the front view and show section AA in its corresponding view. The drawing must be fully dimensioned and appropriately scaled. All dimensions are in mm. Make simple assumption when insufficient information is given. Please submit the assignment by 14th March 2021.

1. Using a ruler, protractor and compass,draw the mechanism to scale, and label all of the angular positions (0,'sand 04's) on your drawing. This should be done on engineering paper, or printer paper. (15 points) 2. Using a protractor measure the anglesand report them. (10 points) 3. Using your MATLAB or Python code, which uses the vector loop equations and the plot vector function determine the velocities and accelerations of points A and B.Publish the results (save as a PDFfile). (20 points) Combine your results for 1-3 into asingle pdf file and upload to Quiz 3(5 points)

Question 4 In each of the following, an object is placed at the center of a "glass box'. Your eye is at the corner of the glass box indicated by the black dot, and you are looking toward the center of the glass box. In each diagram, circle the view (1, 2, 3, 4, or 5) that corresponds to what you would see. 9 8
