Mechanical Engineering HW

The following problems have been selected from your text book (R.C. Hibbeler, Engineering Mechanics: Statics, Ed. 14, Pearson):

Note: Partial solutions and answers to all Preliminary Problems (problems that start with P) are given in the back of the book.

Note: Partial solutions and answers to all Fundamental Problems (problems that start with F) are given in the back of the book.

Hints are provided in the parenthesis. If you don’t know how to solve the problems, study the examples in the textbook and slides.

A. Warm-up problems

(you don’t need to submit the solutions for these problems. The solutions are in the back of the textbook.)

1. F2-5 (vector addition)

2. F2-6 (vector addition)

3. F2-8 (coplanar force)

4. F2-13 (3D force vector)

5. F2-15 (3D force vector)

6. F2-19 (3D position vector)

7. F2-25 (dot product)

8. F2-31 (dot product)

B. Main problems (10 points each)

(you need to submit the solutions of these problems as these problems are graded. Answers are either provided here or in the back of the textbook for you to check the accuracy. You need to write the detailed calculation steps.)
