Question 1: A) Plot the forced-undamped vibration response of a spring-mass system given by Eq. (3.13), page 265 of the Book, for the following sets of data: Set 1: 8st = : 0.17 m, w = 6.15, wn = 7.6 r/s, x₁ = 0.11 m, x = 0.7 m/s Set 2: 8st 0.17 m, w = 7.3 r/s, wn = 7.6 r/s, xo = 0.11 m, xo = 0.7 m/s Set 3: 8st = 0.17 m, w = 7.7,wn = 7.6, x₁ = 0.11 m, x = 0.7 m/s Set 4: 8st = 0.17 m, w = 7.6 r/s, wn = 7.6 r/s, xo = 0.11 m, xo = 0.7 m/s = x(t) = xo cos wnt + xo Wn sin wnt + Est B) Analyze and discuss the results. COS @t 1 - - cos @nt @ @n (3.13)

hand written plz Answer the following questions using the information provided in this unit. Know and Understand 1. True or False? The primary purpose of section views is to help feature exterior detail without using hidden lines. For the next three terms, match the three types of lines to the three descriptions. Answers are used only once. 2. Cutting-plane line 3. Section line 4. Short break line A. Not exclusive to section views, but needed for broken- out sections. B. Drawn thick in a view adjacent to the section view. C. Drawn thin, and usually continuous, but sometimes dashed. 5. Of the following, which is not a type of section view featured in this unit? A. Full B. Half C. Quarter D. Offset 6. True or False? The preferred dividing line between the two halves of a half-section view is the visible line. 7. An object with a number of odd features, such as spokes or holes, often has a(n) section so the odd features can be rotated around the axis into a vertical cutting plane,…

(Compute) What is line OA's direction cosine angle, in degrees, from the x-axis (θx)? Note that direction cosine angles are also known as coordinate direction angles.
