Each of these alternatives has roughly the same constructioncost.a) If p1 = 0.95 and p2 = 0.90, which of the two alternatives should be chosen? (Systems with higher probability of being operational are preferred.)b) If p1 = 0.95, for what range of values of p2 is the single component preferred to the system with two components?c) Below is a picture that shows all the possible pairs of values of p1 and p2. These values are divided into two regions, region I and region II. For p1 and p2 that lie in one of these regions, the single component is preferred. For p1 and p2 in the other region, the system with two components is preferred. Which is which? Justify your answer. (The

to the x-axis from the head of the arrow aright triangle is formed. Using the Pythagorean theorem, with the sides of the triangle representing the x-and y-components of the vector, the algebraic equations, Ax = A ⋅ cosθ , Ay = A ⋅ sin θ and A = Ax2 + Ay2 are self evident. x And of course, it follows that if you are adding two vectors, A and B, you can add the x- components of the two vectors to find the x-component of the resulting vector , Rx = Ax + Bx, and likewise, the y-component of the resulting vector, Ry = Ay + By. Again, using the Pythagorean theorem, the resultant vector is R = Rx2 + Ry2 . The students with strong mathematical intelligence will be able to follow this long

to fulfill our educational objectives, my personal opinion is thatour effort should be directed towards cultivating and increasing the ability ofstudents to think. That the ability to think is more important than the simpletransfer of knowledge is obvious: Even if a student learns everything by the timethe B.S. degree is awarded, a short time after graduation that engineeringprofessional (a) will have to obtain new knowledge, probably on their own (b) it is very probable that a few years after graduation, the young engineer will be the head of a group that involves persons from various disciplines; in that capacity simple, dry knowledge of facts will not be at all helpful; the ability to think, however, will be
. Planning and Evaluation for Concurrrent Engineering A key to making this project work is the combined use of (a) concurrent engineeringtechniques and (b) a team-based management by objective (MBO) and peer review technique forplanning and evaluation of performance. Evaluation of personnel performance in concurrentengineering projects is a difficult task in industry, as well as in the classroom. However, thecombined use of concurrent engineering and team-based MBO planning and peer reviewevaluation techniques has enabled realistic and effective planning of activities and evaluation ofperformance related to those activities.Concurrent Engineering Turino (1992) defined concurrent engineering as "a systematic approach to the integrated

used to adjust the instructor’s group grade for each student. For example,suppose the instructor assigns a grade of B (85%) to the group project. Based on the students’evaluations, the global average for the group is 90%. If student Y’s individual average is 80%,this variation of -10% (80%-90%) is applied to the group grade of 85%, and student Y receives agrade of 75%. This method allows for individual differences to be accounted for, but relies onthe instructor’s experience as a basis for the grade.OVERVIEW OF THE CURRENT COURSEThe last year has led to a few new developments related to the course. One is that two excellentbooks were found that are much more relevant to the overall course. One is Design for Societyby Nigel Whiteley.10

Thefollowing three test beams are used for our finite element integration. 1. A rectangular beam with a hole, to determine stress concentration factor (Fig. 2). Three gages, are mounted on the beam at various distances from the edge of the hole along the width of the beam. 2. A constant stress beam with two tapered sections for constant stress (Fig. 3).

The apparatus consists of a transparentplastic tube fitted at one end with a twin loudspeaker enclosure, and at the other with a heavysample holder on which the sample material is mounted. A small microphone may be movedaxially along the length of the tube and its position measured.The loud speakers are fed with a variable common pure tone (single frequency) from a functiongenerator and the sound waves produced pass along the tube sample. According to the type ofmaterial and frequency, part of the sound energy is absorbed, and the remainder reflected backalong the tube. The latter is detected by

On the other hand: (a) the continuousexpansion of the content to be covered (with a soaring number of new topics and techniquesbrought into the curriculum); (b) the flexibility of the curriculum and options to be madeavailable to students and (c) also a more student-centered approach being recommended in highereducation requiring more staff time and more physical resources to run courses.

. A Swift Kick Toward DesignBetween the second and third year offerings of AE 243, I had the opportunity to co-teach a seniorlevel design course with Dr. Ronald Yoder (see Raman and Yoder, 1997a & b for details). Ourexperiences during the first semester of this course profoundly influenced my goals for AE 243:Specifically, incorporating design, independent learning, and computer use were prioritiesbecause our senior engineering students were uncomfortable with all these activities. Therefore,in the spring of 1996, AE 243 was taught with a significant emphasis on design and teamlearning. Third Year’s ExperiencesSix students were enrolled in AE 243 in the spring 1996 offering of the course. The
