Engineering materials - selection
In the design of machinery in general, a vast variety of materials of both organic and inorganic origin is utilized. We generally think of metals as the usual materials of design, but, although used to a lesser...

Statics
Static deals with the conditions of equilibrium of bodies acte upon by forces and is one of the oldest branches of science. When several forces of various magnitudes and directions act upon a body, they are said to constitute a system of forces. The general...

The importance of mechanics in the preparation of young engineers for work in specialized fields cannot be overmphasized. The demand from industry is more and more for young men who are soundly grounded in their fundamental subjects rather than for those...

Descriptive geometry and mechanical drawing
Descriptive geometry
Is a mathematical-graphical procedure that has for its purpose the visualization of structures and their exact representation in drawings. After analysic of any structure, each element is shown in the drawing in its exact geometrical...

Power and Efficiency
Rate of doing work: power
In practice, where work is done upon a body, both the amount of work and also the time during which that work is done are important. For example, if a motordriven soist has to raise its load quikly, a more powerful hoist and a larger driving...

Nuclear Energy
The fundamental source of power
In the last fifty years we have learned more about the fundamental structure of metter than in all history. Today we know that the rearrangement of the particles comprising the atom accounts for all the energy in the universe. And we are just...

Work
Work is applied to any form of labor, pysical or mental, for producing any kind of result. In science and engineering, on the other hand, "work" has a definite technical meaning, which the following illustration will make clear.

The laws of motion and universal gravitation
Newton's laws of motion.
Sir Isaac Newton (1642 - 1727), one of the most profound scientists of all time, interpreted and correlated many observatiorions in mechanics and combined the results into three fundamental laws, known as Newton's laws of...

Matter, force, motion, and friction
The concept of matter.
We know that physics began with the more or less qualitative passive observation of obvious natural phenomena, such as the downward motion of a freely falling body, the tides of the ocean, the lightning, the rainbow, the mysterious...

Branches Of Engineering
Engineering has been defined as the art of directing the great sources of power in nature for the use and convenience of man. In its modern form the practice of engineering involves men, money, materials, machines and energy. It is differentiated from science because it...
