Latest Basics of Design Engineering Content

Acrylic-styrene-acrylonitrile (ASA) polymers are amorphous plastics which have mechanical properties similar to those of ABS resins.

Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of rotation.

In order to control noise, designers must first determine where the noise source or sources are how much each is contributing to the overall level, and their frequency signatures.

Bearings that require a separate pressurized lubrication system need more space than self-lubricating types.

Centralized lubricating systems lubricate all the friction points from a single pump source.

Valves are essential elements for controlling fluid system performance.

Commercial quality "aircraft" grade cable and wire rope are mechanical devices consisting of multiple wires or strands, helically wound or laid about an axis.

Rolling-element instrument bearings are precision bearings that include at least one of the following characteristics.

In addition to resisting HCl at all concentrations and at temperatures above the boiling temperature, zirconium and its alloys also have excellent resistance in sulfuric acid at temperatures above boiling and concentrations to 70%.

Sealants are categorized as hardening and nonhardening.

The ability to construct accurate, easily modified models is helping make manufacturers more competitive.

Polybenzimidazole (PBI) was first polymerized by scientists in the 1950s.

Parts can be fastened by a rivet if flat parallel surfaces exist for both the rivet clinch and head, and there is adequate space for the rivet driver during clinching.

Hose clamps are made in a variety of types to match load, assembly, and cost specifications.

Spring clips use compressive spring force to secure assembly components.
