If you grab each end of a pencil and try to pull the ends apart, you are putting the pencil under tension or tensile stress; if you push the ends toward each other, you are putting the pencil under:
A.) compression
B.) tension
C.) fracture
D.) both A and B are correct
(please do not answer if you are not completely sure)
tensile stress : stress that tends to lengthen the material
compressive stress : tress that tends to compress the material
hence the answer is A) compression

You should test out your script using the following matrices. 2 3 1 2 3 1 C D- 3 2 B- A- -3 8 4 8 2 4 4 1 You may not use any special MATLAB tools. Instead, work symbolically and derive general expressions for the eigenvalues and the eigenvectors. For instance, you may not use the SOLVE function.

Your boss hands you a bag containing four springs, A, B, C, and D, and tells you that they all have the same relaxed length. He wants you to rank them by the values of their spring constants. He locks you in a room with only the springs, a ruler, and a pad and pencil, and tells you to knock when you're done. Each spring has a hook on one end and a handgrip on the other. There is nothing...
Course Project Brainstorming Each course requires you to complete a Course Project. In most cases, that project will be a paper that deals with a topic related to the course content. Your instructor may have additional requirements. In general, the Course Project paper should be between 1600 to 1700 words in length, 12 point font, double-spaced; and must use APA format for both in-body citations and the reference page at the end of the paper. The individual Course Project Assignments...

1. Monetary Operations Under a Gold Standard. It is 1900 and most of the world is operating under the gold standard. In Pogo, the central bank starts 1900 with 120 M in gold reserves and 80M in domestic assets consisting of Pogo Treasury Bills and perhaps loans made to member commercial banks (domestic assets). It has 200M in liabilities in the form of deposits made by its member banks as well as Pogo Reserve Notes held by the non-banking public....
