Moreover, FRP ducts are lightweight, which significantly reduces the installation time and labor costs. Their light weight also lessens the load on building structures, making them suitable for high-rise buildings and other large-scale projects. In addition, the non-conductive nature of FRP minimizes the risk of electrical hazards, enhancing workplace safety In addition, the non-conductive nature of FRP minimizes the risk of electrical hazards, enhancing workplace safety

- Double Iridium spark plugs have revolutionized the automotive industry with their exceptional durability and improved performance capabilities. These advanced ignition devices are the epitome of engineering innovation, combining cutting-edge technology with robust materials to deliver unparalleled efficiency.
- Introduction to Iridium Spark Plug
On some engines you have to remove the clutch-housing cover to reach the rear nuts.

spark plug o ring. It is important to regularly inspect the O-ring during routine maintenance checks and replace it if necessary. A worn or damaged O-ring can lead to oil leaks, engine misfires, and other issues that can affect the performance of the vehicle.
The small little oil seal has an outsized role in power transmission.

Meanwhile, rubber-cased oil seals are used under conditions where a metal-cased seal can fail (for example, because of thermal expansion). Unlike the metal-cased type, these seals do not rust. Moreover, they can seal a lightly damaged housing better than metal-covered seals since, in high temperatures, rubber can provide a more stable sealability.
A) Shaft runout
As shown in Figure 8, shaft runout is defined as being twice the eccentricity between the shaft center and center of shaft-center rotation trajectory.
