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

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.

The most reliable means for changing shaft speed remains a mechanical variable-speed transmission.

Metal-chain drives are normally used for applications below 3,000 rpm where accuracy and reliability must be greater than that provided by rubber belts.

Sealants are categorized as hardening and nonhardening.

Mechanical face seals are a good choice when minimum leakage of the sealed fluid is the most important criterion.

A gasket provides a barrier against fluid transfer across mating static surfaces.

The function of an axial face seal, like felt radial seals, is to protect bearings from contaminants.
