During the French Revolution, the voting by estates was a system in which the representatives of the three estates - the clergy, the nobility, and the commoners - each had one vote. This system was used in the Estates-General, the legislative body of France at the time. Despite the fact that the third estate (commoners) represented the majority of the population, they were often outvoted by the clergy and nobility, who held more power and privilege. This unequal voting system was one of the factors that led to the discontent and eventual overthrow of the monarchy during the revolution. **

Self-lubricating properties refer to the ability of a material to reduce friction and wear by providing its own lubrication without the need for an external lubricant. This is often achieved through the inclusion of solid lubricants such as graphite, molybdenum disulfide, or PTFE within the material matrix. Self-lubricating materials are commonly used in applications where traditional lubricants are not practical or where maintenance-free operation is desired, such as in high-temperature or vacuum environments. **
