Explanation Given: Briefly describe, in words, the effects you would expect in the situation given. “Your friend is calling to you from across the street in New York City, with a shout that registers 90 d B . Traffic is heavy, and several emergency vehicles are passing by with sirens.” Decibel Scale: To avoid expressing sound in terms of P a , which involves some very big numbers and some very small numbers, the decibel or d B scale is used. The decibel or d B scale uses the hearing threshold of 20 μ P a or 20 × 10 − 6 Pa as the reference level. This 20 μ P a or 20 × 10 − 6 is defined as 0 d B . Decibels Times as Loud as Softest Audible Sound Example 140 10 14 Jet at 30 meters 120 10 12 Strong risk of damage to human ear 100 10 10 Siren at 30 met...

Problem 5 ( Marybeth is also interested in the experiment from Problem 2 (associated with the enhancements for Captain America's shield), so she decides to start a detailed literature review on the subject. Among others, she found a paper where they used a 2"(4-1) fractional factorial design in the factors: (A) shield material, (B) throwing mechanism, (C) edge modification, and (D) handle adjustment. The experimental design used in the paper is shown in the table below. a.

Based on the resolution of this design, what do you think about the generator used in the paper? Do you think it was a good choice, or would you have selected a different one? Explain your answer in detail.
