More Information
Lubricants are crucial in maintaining mechanical systems by reducing friction, which minimizes wear and helps in dissipating heat efficiently. Synthetic lubricants are preferred in certain settings for their superior thermal stability compared to mineral oils.
Tips
A common mistake is confusing the reduction of friction with increasing it, and assuming water is a lubricant due to its liquid nature. Remember, lubricants primarily minimize friction.
