Latest Basics of Design Engineering Content

Any fluid system may need to measure pressure, flow, or fluid level.

Conrad or deep-groove bearings are the most widely used ball bearings.

There is no doubt that finite-element analysis is getting a bigger role in development projects.

Specialty bearings appear in many shapes and sizes.

Three major components in any fiber-optic system are the transmitter, receiver, and fiber cable.

Power operational amplifiers (POPs) are becoming increasingly common in control circuitry.

As engineering models increasingly are described by solid models, there has been a change in the character of hardcopy output devices found in engineering labs.

Cellulosics are synthetic plastics, but they are not synthetic polymers; they are made from a naturally occurring polymer, cellulose, which is obtained from wood pulp and cotton linters.

Nonmetallic materials offer self-lubricating properties, high-temperature stability, solvent resistance, or low cost.

Power-circuit modules containing several power semiconductor switching devices can reshape ac power into other required forms and often have current ratings from 30 to 50 A.

The variety of plastic chain available includes traditional designs with discrete links that connect to form almost any length, and newer designs that include one, two, and three parallel strength members.

Power-control modules are circuits comprising devices such as silicon-controlled rectifiers, triacs, power transistors, and power rectifier diodes.

These nuts are squeezed into round, punched or drilled holes in sheet metal between a parallel punch and flat anvil.

Cast irons include many metals having a wide variety of properties.

These nuts are internally threaded, precision, work-hardened steel with external undercuts on two sides.
