1.A 100 lb force vector F is aligned from A to B. Point A is located at the coordinates (2, 2, 2) and point B at (4,5,6). Calculate the moment of F about the y axis.
2.Go to the weather channel web site (www.weather.com)and look up the monthly average temperature for a major metropolitan area and nearby rural area anywhere in the world over a 12 mo. period. Use the data you looked up to estimate the magnitude of the urban heat island effect for that city. Graph your data in two figures, and determine the temperature differences in each month.
