The W12 * 50 is made of A992 steel and is used as a column that has a length of 20 ft. If the ends of the column are fixed supported, can the column support the critical load without yielding?
Geography 101: Notes taken, interpreted, and formatted by: Jensine Bonner Week 7 of Notes: 3/21/16 The Sahel (In Africa) is… An area between the Sahara Desert - In this area, there will be (1) wet summer, and (1) dry winter in the course of a year (Sudan, Chad, Niger, Mali, and Senegal) There are (5) regions on the earth that pertain to wind N. Polar High - 90 N, 80 N - Snow + Ice N. Subpolar Low - 70 N, 60 N - Storms N. Subtropical High - 35 N, 30 N - Deserts Equatorial Low - 5 N, 5 S - Rainforests S. Subtropical High - 30 N, 35 N - Deserts S. Subpolar Low - 60 N, 70 N - Storms S. Polar High -Snow+Ice - 80 N, 90 N Thermally Induced Equatorial Low N+S Polar Highs Mechanically induced N+S Subtropical High N+S Subpolar Low *Need to know* Warm air always rises. (The warm air comes from the equatorial low) Cold air descends, which causes higher air pressure (The descending air flows towards the equator) In S. Pole ice can be 2 miles thick In the N. Pole the ice is not as thick since the ocean in underneath 3/23/16 Wind The Coriolis Force The deflection that is caused by the Coriolis Force occurs in the right of the path that it is intended to travel in the northern hemisphere, and to the left in the southern hemisphere The strength from the Coriolis Force increases as the latitude increases This force is nonexistent at the equator, but full force at the poles Trade winds These are between N. Subtropical High, Equatorial Low, S. Subtropical High These winds are…. Most extensively and best developed wind system Consistent in both speed and direction Between: N. Subpolar Low, N. Subtropical High, S. Subpolar Low, & S. Subtropical High Are all affected by westerly winds called (Westerlies) Between: Polar High, N. Subpolar Low, S. Polar High, & S. Subpolar Low are all affected by easterly winds (Polar Easterlies) Horse Lats. (latitudes) What the subtropical high Years ago, ships that traveled this area horses were thrown overboard to make the ship lighter Windward Leeward Facing the wind Facing opposite the wind N. Hemisphere the air flows clockwise The Wind direction affects wind pressure and temperature End of Week 7 notes. I hope that they were helpful to you. Notes will be uploaded weekly, so be sure to come back again! - Jensine
