MAE 206 Engineering Statics

MAE 206 Engineering Statics (Fall 2006)

Note to Students (11/28): About the homework assignment due tomorrow.

1) Please do not hand in SII.1:2,4. It will not be graded.

2) Turn in your MATLAB code and the figure of the displaced truss for S5.5: 1,4,6,10. The scaled displacements are obtained by letting index = 0. The values that you provide in the code for stretch do not effect the scaled displacements, the member forces, or the reactions because the trusses in these problems are statically determinate.

Note to Students (11/15): A few things....

1) The homework that was due on Monday, November 20 is now due right after break on Monday, November 27.

2) The design project is due on the last day of our regularly scheduled class on Wednesday, December 6. This date is fast approaching, so within each team each of the members should complete their individual designs by about November 27 (when you get back from break) to leave enough time to complete the final design (See design report).

3) The design project is counted the same as 10 homework problems. The top 3 teams will receive bonus points worth 5 homework problems.

4) For design groups of less than 4: On Monday, when we return from class, I will ask these teams to consolidate into teams of 4. At this point, each of you should have already completed your individual designs for the project.

Note to Students (11/14): The computer class this Wednesday, November 15, is in the computer lab, BR1403.

Reminder: The regularly scheduled class on Wednesday, November 11 is cancelled, as well as the next class on Monday, November 20. Attendance at the computer class is mandatory.

Note to Students (11/8): The needed material for the design project is given below.

1. DESIGN REPORT - The design project is described here. It follows the same format as the report you hand in.

2. DESIGN - General description about engineering design

3. MATLAB & TEMPLATES - A MATLAB tutorial and templates that give the syntax for graphing, arrays, and functions

Note to Students (11/8): The solution to test 3 is here.

Note to Students (10/5): Corrections:

Problem 4.5 - 68: The weight is W = 240 lb; Problem 4.5 - 78: The weight of each post is 40 lb; Problem 4.5 - 72: The radius is 1 ft.; Problem 4.4 - 274: The solution is 0.935 lb (not 0.735 lb).

Note to Students (10/16): Please mark these corrections on your syllabus:

On day 17: The homework (the 3rd set in S4.2) is due on day 19 (not day 17).

On day 18: The homework (the 4th set in S4.2) is due on day 19 (not day 17).

TEST 3 is on NOV 8 (not OCT 8).

Note to Students (10/16): The solution to test 2 is here.

Note to Students (9/29): TEST 2 HAS BEEN MOVED ONE CLASS PERIOD TO MONDAY, OCTOBER 9.

Note to Students (9/28): Corrections:

Problem 3.3 - 19: The solution should be 41.0 lb-in not 41.0 lb-ft.
(Also in the text, the 45 lb-ft should read 45 lb-in)
Problem 3.4 - 13: The companion sketch is Problem 3.4 - 44 not 3.4 - 24.
Problem 3.4 - 30: In the drawing, the distance on the right side should be 21 in not 19 in.
Problem 3.4 - 44: The solution given for RD should be in the i direction instead of the j direction.

Note to Students (9/22): Corrections:

Problem 3.2-19: Point A is the origin of the coordinate system.
Problem 3.2 - 25: You do not need to turn this one in.

Note to Students (9/18): The solution to test 1 is here.

SET 11 SET 12 SET 13 SET 14 SET 15

Note to Students (8/29): Your teaching assistant for this class has been assigned. His name is Jason and his email is jzhu@ncsu.edu. He will be holding office hours in Broughton 3196 twice-a-week; on Mondays from 10:30am to 11:30am and on Fridays from 1:00pm to 2:00pm.

Note to Students (8/23): Welcome to your engineering statics course link. Please bookmark this page, and make hard copies of the syllabus and course description linked above. Notices will be posted here, so it will be good to check this page out from time to time.

Your text book for this class can only be picked up at Pack Backers Book Store on 2900 Hillsborough Street. Pack Backers is located on the north side of Hillsborough Street just west of Dan Allen Drive. The textbook is entitled "Engineering Statics," by L. Silverberg and it comes in two volumes. The text book will be available at that bookstore on and after Wednesday, August 23.

Also, notice that your first hw assignment is due this coming Wednesday, August 30.
