Copy of Class Syllabus: 1/19 First day of class: Chapter 1, no homework 1/21 Chapter 1; **Do the following four conversion problems**: 1. 3g/m^3 =slug/f^3 2. 3N = lb 3. 3f/s = m/s 4. 3.0 slugs= kg 1/24 Chapter 2; Do problems 2.1 and 2.3 1/26 Do problems 2.44 and 2.48 1/28 NO CLASS! 1/31 Do problems 2.63 and 2.67 2/2 Do problem 2.72 2/4 Do problem 2.86 WORKSHEET FOR 3-D VECTORS (ANGLES or DISTANCES GIVEN): 2/7 Do problem 2.105 (or 109) 2/9 Exam #1 Chapters 1 & 2 2/14 Do problem 3.5 2/16 Using the vectors from problem 3.45b): if **P** is a moment arm **r** and **Q** is a force **F**, find the moment about point o of the vectors **r** and **F**. 2/18 Do problem 3.22 2/21 No homework; guest speaker in class today! 2/23 4.1, 4.105 (or 4.106?) 2/25 Homework; finish problem 4.132 do problem 4.133 2/28 PRACTICE QUIZ FOR Extra Credit: Do the following problems: 1. 3.45a using directions from Feb 16 above 2. 4.5 or 4.6 3. 4.132 3/2 Exam #2 Chapters 3 & 4 3/7 Finish problem 3.35, and find the angle between the vectors in each problem. Using the vectors in Problem 3.45 part b, find the mixed triple product of S, P, and Q. Do problem 3.46 (coplanar means something about the value of the mixed triple product; namely, the cross product, which is perpendicular the the plane of the vectors, is also perpendicular to the first vector. this means that the angle between S and PXQ is 90 degrees, and the cosine of 90 degrees is zero; therefore the mixed triple product is zero. 3/9 Go over tests in class; no homework. 3/11 3.48; take moments about the Y-axis and the lid diagonal BD. 3/21 Finish Chapter 3: Couples and equivalent force-couple systems; do problem 3.101 (we did parts a. and f. in class) 3/23 Chapter 5 Problems 5.2 and 5.5 3/25 Chapter 5 Problem 5.29 3/28 Chapter 5 Centroids by direct integration Problems 5.36 Smartboard notes for direct integration:
