Different types of fit include clearance fit, interference fit, and transition fit.

• Clearance fit: parts are designed to have a gap between them, allowing for easy assembly and disassembly.

• Interference fit: parts are designed to be pressed or forced together, creating a tight and secure fit.

• Transition fit: parts have a small amount of overlap, creating a balance between clearance and interference fit.

• Examples include pi...read more
