Q3. Explain 3,2,1 principle of GD &t
Ans. 
The 3,2,1 principle of GD&T is a method used to establish a datum reference frame for geometric dimensioning and tolerancing.
• 3 points are used to establish a datum plane, 2 points to establish a datum line, and 1 point to establish a datum point.

• The 3,2,1 principle ensures that the part is securely located and oriented in a consistent manner for measurement and manufacturing processes.

• Datum features are used as referen...read more

Q2. What is hardness
Ans. 
Hardness is a measure of a material's resistance to deformation, scratching, or abrasion.
• Hardness is a physical property of materials.

• It is typically measured using tests like the Mohs scale for minerals or the Rockwell scale for metals.

• Materials with higher hardness values are more resistant to wear and scratching.

• Hardness can be influenced by factors such as composition, microstructure, and processing.

• Examples of har...read more

Q2. Types of fit? Ans-According to ISI system fit are deivde in two three parts provide 1 clearance fit. 2 Interference fit 3 transition fit.
Ans. 
Types of fits include clearance fit, interference fit, and transition fit.
• Clearance fit: parts are intended to have a gap between them

• Interference fit: parts are intended to be pressed or forced together

• Transition fit: parts have a combination of clearance and interference fit

• ISI system divides fits into these three categories

• Fits are important in ensuring proper functioning of mechanical systems

Q3. What is tollerance? Ans-The permissable very action of a size is called tollerance.
Ans. 
Tolerance is the allowable variation in a dimension or measurement.
• Tolerance is important in engineering to ensure that parts fit together properly and function as intended.

• It is usually expressed as a range of acceptable values, such as +/- 0.1mm.

• Tolerance can be affected by factors such as manufacturing processes, materials, and design requirements.

• Tolerance can also be used to control the fit and clearance between m...read more
