Next, we discuss the 40% figure, which can denote the allowable leakage rate for particular types of oil seals. Leakage can severely impact the overall performance of mechanical systems, leading to reduced lubrication and increased wear on components. A reputable oil seal must minimize leakage to a level that is often benchmarked at around 40% of the maximum allowable threshold for that system. Manufacturers pour significant resources into developing materials and designs that can achieve this standard, as minimizing leakage not only conserves lubricant but also enhances the efficiency and longevity of the machinery.

Roman double tiles were not just about practicality; they were also a canvas for artistic expression. Some of the tiles discovered by archaeologists bear decorative elements such as inscriptions, motifs, and even intricate designs that reflect the aesthetics of the time. Such embellishments could indicate the status of the building owner or the significance of the structure itself. These artistic dimensions remind us that even functional items in ancient Rome were often imbued with meaning and beauty.
