The percentage of shear studs used in a metal deck, often referred to as shear stud percentage, is a critical factor in structural design. It depends on several variables, including the size and spacing of the studs, the type of metal deck, and the specific load requirements of the project. Engineers carefully calculate this percentage to ensure optimal performance while avoiding overloading or underutilization Engineers carefully calculate this percentage to ensure optimal performance while avoiding overloading or underutilization
- Another breakthrough was the integration of artificial intelligence (AI) and machine learning algorithms into spark plug design
- The 'Diamond Fire' in E3's name refers to their unique diamond-shaped electrode design, a groundbreaking concept in the world of spark plugs. This distinctive shape is not just a cosmetic feature; it significantly enhances the plug's performance by providing a larger surface area for the spark to jump. This results in a more robust and consistent ignition, leading to improved fuel efficiency and a smoother engine operation.

Oil seal size
Vulcanizates of several fluoroelastomers, listed in Table 14.1, were exposed to a standard 5W-30 engine oil, ASTM Service Fluid 105, for up to 6 weeks at 150°C (302°F).5 The oil was changed weekly, but was not aerated. Retained elongation was measured after exposure for 1, 2, 3, and 6 weeks; data are shown in Fig. 14.3. The results indicate that bisphenol-cured FKM-A500 VDF/HFP copolymer, FKM-B600 VDF/HFP/TFE terpolymer, and peroxide-cured FEPM-7456 TFE/P/VDF terpolymer lost most of their original elongation over the course of the test exposure, indicating considerable additional cross-linking occurred by reaction with amine- and phenol-containing oil additives. The other fluoroelastomers showed better retention of elongation, being much less susceptible to additional crosslinking. Note that FEPM-7456 contains a high level of VDF (about 30%), while FEPM-7506 contains a relatively low VDF level (10–15%) to serve as cure site for bisphenol curing. The other FEPM types contain no VDF.

WHICH MATERIALS MAKE UP SEALS?
b) The area where the oil seal is seated is to be plunge ground in order to prevent wear grooves that normally tend to wear out the lip of the oil seal at a faster rate.
First, an elastomer, most often nitrile, is vulcanised to a metal ring. This creates a stiffening effect that includes a specialised metal tension spring directly behind the sealing lip, keeping the oil seal firmly in place against the moving part.
The oil seal manufacturing industry continues to witness innovations aimed at enhancing the performance and reliability of seals. Advancements in material science, seal design, and manufacturing processes have led to the development of seals with improved durability, resistance to extreme conditions, and enhanced sealing capabilities. These innovations contribute to the overall efficiency and longevity of machinery and equipment in diverse industrial sectors.
