Engineering Workshop Proficiency: Introduction to Fits & Tolerances

AI Tutorials & Future Tech on Instagram: "This technique is called shrink fitting or cryogenic fitting. Engineers cool one component with liquid nitrogen so it physically contracts. The second component stays at room temperature. When assembled, the cold part warms, expands, and creates an ultra-tight interference fit without bolts, welding, or adhesives. This method is used in turbines, heavy machinery, aerospace parts, industrial shafts, and precision gear assemblies where tolerances must be p
