General Questions And Answers In Engineering and Technology

Engineering Technology - Engineers

Engineering is an art of applying science to the optimum conversion of the resources of nature to the uses of humankind. It is based principally on physics, chemistry, and mathematics and their extensions into materials science, solid and fluid mechanics, thermodynamics, transfer and rate processes, and systems analysis. It is thus "the practical application of science and math to commerce or industry". In other words "the art or science of applying scientific knowledge to practical problems".

Advantages And Disadvantages Of Computer Aided Design (CAD) Over Manual Drafting

Sample CAD drafting work

The advantages of CAD include: the ability to producing very accurate designs; drawings can be created in 2D or 3D and rotated; other computer programmes can be linked to the design software. With manual drafting, you must determine the scale of a view before you start drawing. This scale compares the size of the actual object to the size of the model drawn on paper. With CAD, you first decide what units of measurement you will use, and then draw your model at 1:1 scale.

Value Engineering and Its Importance In Engineering Industry

Value Engineering

The value is a function of cost. Therefore, it can be increased either by improving the function or reducing cost. The maximum value is achieved when the function performs reliably at the lowest cost. A key principle of value engineering that basic functions be preserved and not reduced as a result of improvements in value. Thus Value Engineering (VE) is a systematic method to improve the "value" of goods, products or services through an examination of the function.
