A cable gland provides strain-relief and connects by a means suitable for the type and description of cable for which it is designed—including provision for making electrical connection to the armour or braid and lead or aluminium sheath of the cable, if any.
Ford used several models over the years. They were coded by the color of the plastic wire strain relief, or "grommet" as it is most often called, in order to make them easy to identify. In addition to the color-coding, the modules may have a keyway molded into the electrical connectors to prevent accidental use in the wrong vehicle.
The series can support the same strain as a single insulator, but the series provides a much higher effective insulation. [2] If one string is insufficient for the strain, a heavy steel plate effectively bundles several insulator strings mechanically. One plate is on the "hot" end and another is located at the support structure.
Tight fitting rubber grommets can also prevent the entry of dirt, air, water, etc. [6] The smooth and sometimes soft inner surface of the grommet shields the wire from damage. [ 6 ] Grommets are generally used whenever wires pass through punched or drilled sheet metal or plastic casings for this reason. [ 6 ]
These techniques function using a "strain release" principle; cutting the measurement specimen to relax the residual stresses and then measuring the deformed shape. As these deformations are usually elastic, there is an exploitable linear relationship between the magnitude of the deformation and magnitude of the released residual stress. [4]
The stress relief treatment resulted in 47% growth of the original, large peak, while it shifted to the left 28-RPM (less than 0.75%). Figure 5: Vibratory Stress Relief was performed on this mild steel weldment weighing almost 12 tons. Overall size was 17' × 15' × 2' (≈ 5.2 × 5.6 × 0.6 meters).
A expansion joint, or movement joint, is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials. They are commonly found between sections of buildings , bridges , sidewalks , railway tracks , piping systems , ships , and other structures.
A rupture disc (burst) Pressure-effect acting at a rupture disc A rupture disc, also known as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.
