Describes an approach to teaching engineering design that involves analyzing, designing, building, and testing a simple structure. Explains the procedures for the various activities and discusses how the design concept can be incorporated into other courses. (ML)

This paper discusses the mechanization of mathematical functions by means of analog electronics. Five different approaches are described which demonstrate the versatility of the analog technique by using parabolic function, exponential decay technique, projectile trajectory, trigonometry, and piecewise linear approximation techniques.

Describes an image database system assembled using separate computer components that was developed to overcome text-only computer hardware storage and retrieval limitations for a pavement design class. (JJK)

Describes a two-semester-hour freshman course in engineering graphics which uses both traditional and computerized instruction. Includes course description, computer graphics topics, and recommendations. Indicates that combining interactive graphics software with development of simple programs gave students a better foundation for upper-division…

Develops a programed approach for developing design projects. Describes the initiation, design experiences, final report, and problems of the approach. (YP)

Illustrates how triangular diagrams can aid in presenting some of the rather complex transient interactions that occur among gas and surface species during heterogeneous catalytic reactions. The basic equations and numerical examples are described. Classroom use of the triangular diagram is discussed. Several diagrams and graphs are provided. (YP)

A graphical illustration is presented indicating how the mean proportional (geometric mean), once established for one set of conditions of a geometric identity, can be used to generate other sets of conditions for the same identity. Exemplified is the application of this principle in developing graphical solutions to engineering problems. (JJK)

Described is a computer algorithm for obtaining the coordinates of vertices, chord factors, and dihedral angles for plotting orthographic and axonometric projections, and for tabulating chord lengths and dihedral angles. (Author)

Described are improvements for the computer efficiency of the two midpoint scan-conversion algorithms used to draw ellipses. Included are computer programs written in C programing language. (JJK)

Indicates that increased exposure to different objects in teaching orthographic projection benefits students, especially when they can manipulate and see the surfaces, points, and lines simultaneously or sequentially in three views. Positive attitudes and increased scores were noted after students used interactive computer graphics in an…

Describes the importance of communication skills to engineers. Gives a step by step method for preparing and giving a professional presentation at the corporate level in engineering. Suggests uses of graphic aids in presentations. (CW)

Describes a three-dimensional computer aided design software package, CADKEY, for demonstrating orthographic orthodirectional projection theory to a classroom. Provides several figures for showing the demonstrations. (Author/YP)

The development of a computer program, called UC SIGNAL, that permits a student to develop a diagram of a control system configuration using an IBM AT or a PS/2 computer is described. The features of UC SIGNAL and its contribution to process control instruction are discussed. (KR)

Offers a method for interactive design of objects on a computer. Outlines a method which allows the designer to interact with orthogonal views to construct a three dimensional model of an arbitrary shape. Presents an algorithm based on the Bezier curves to efficiently create smooth curves and surfaces. (CW)

Discussed is a method to teach undergraduate students how to complete a conceptual design. Presents three tools to use: (1) how to use order-of-magnitude arguments to simplify problems, (2) how to derive design heuristics, and (3) how to decompose large problems into a set of small, simple problems.
