The new ASME Y14.5, 2009 standard on dimensioning and tolerancing reflects a culmination of effort extending over 15 years.

The authors of "Shoulder-fillet stresses finesse" clarify stress-calculation procedures.

The engineering handbook Roark's Formulas for Stress and Strain has been computerized to run in Excel.

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

Many factors enter into the selection of a sealant, not the least of which are final application and cost.

Basic dynamic load rating is the load at which 90% of a group of bearings can survive 1 million inner-race revolutions.

All wire rope and mechanical cable are fabricated from individual wires helically twisted into a strand.

Traction drives have been around for a long time but have not made a major impact on the power-transmission industry.

The primary factors affecting seal selection are temperature, wear resistance, abrasion, sealed pressure, face materials, vibration, and expected life.

Bearings materials are classified as through-hardened materials (used largely for ball bearings) and case-hardened materials (used largely for roller bearings).

Automatic and manual vehicle transmissions have always been competitive with each other.

Some unusual machinery configurations are best served by belts able to deliver power from both top and bottom surfaces.

There are three methods of transmitting power mechanically from shaft to shaft: chain drives, gears, and flexible belts.

Single-point lubrication is similar to separate lubrication because each friction point is distinct.

Pulsating loads, such as those generated by internal combustion engines and compressors, present special problems for V-belt drives.
