Oakes; Problems:

  1. 7.7- Measure the height of your class building using two different methods. Which is
    more accurate? – Option 1: You need to estimate the height of the observatory adjacent to
    Research Hall just north of the Nguyen School of Engineering. Use two different estimation
    methods as discussed in class. (2 points)
    • Use the following information to solve the problem: When seeing the top of the observatory a 45
    degree angle, your approximate distance to the center of the observatory is ~100 feet. Each floor
    of the adjacent building (Research Hall) is about ~20 feet tall.

    Option 2 – Find a multi-story building on your own that’s near you, and use the estimation
    techniques we discussed in class to estimate its height. Please include a digital picture of it in
    your HW Word or pdf document.
    Were your answers close? If not, account for the difference.
  2. 7.9 – How high do the letters on an expressway sign need to be readable? Make some
    reasonable assumptions, e.g., if you can read ¼” letters at 2’ from the computer screen, how large should
    the letters be at 200’ and be readable? (1 point)

  3. Download MATLAB or Octave from the following website:
    https://www.gnu.org/software/octave/download.html
    Now run the following code (copy-and-paste it) after the “>>” (command) prompt:
    x = [0:5:100];
    y = x;
    plot(x, y)
    Copy-and-paste the plot onto your HW solutions page. (1 point)
