Processes, Tools, 3 and Materials of Technology

The development of tools moved from simple to complex. The fi rst tools were hand tools and muscle-powered. Cave dwellers used them for hunting and gathering—a tree limb became a club. With tools, people changed materials they found in nature. The fi rst machine tool was created when an inventor attached a mechanical power system to a hand tool.

Fundamental Principles of Mechanical Design

Mechanical Design Fundamentals K. Craig 8 • Self-Principles – Use an object’s geometry or other property to prevent a problem. • Stability – Stable, neutrally stable, and unstable effects can help or hurt. Some things can be made neutrally stable and fast, while vibration can induce instability. Beware of buckling of compression members.

Examples of Pneumatics: Common Uses in Daily Life

The term pneumatic is used to describe a mechanical device that is powered by compressed air. Systems based on pneumatics rely on compressed air. The energy produced by pneumatic systems can be more flexible, less costly, more reliable, and less dangerous than that produced by devices powered other ways, such as with actuators or electric motors.

Jul 04, 2018·Pliers are some of the handiest tools to have around because they can be used for cutting, twisting, clamping and more. When we look for a pair of pliers to purchase, we always take note of the handle material, how tight the hinge feels, how precise the cutting surface or teeth are in the jaws and of course the over all quality of the tool.

Mathematical Modeling of Control Systems

The dynamics of many systems, whether they are mechanical, electrical, thermal, economic, biological, and so on, may be described in terms of differential equations. Such differential equations may be obtained by using physical laws governing a partic-ular system—for example, Newton’s laws for mechanical systems and Kirchhoff’s laws
