Q3. Isometric to orthogonal representation
Ans. 
Isometric and orthogonal representations are two different ways to depict objects in engineering and design.
• Isometric representation shows objects in a 3D perspective with all three dimensions equally foreshortened.

• Orthogonal representation shows objects in a 2D format with each dimension shown separately and to scale.

• Isometric drawings are often used in technical drawings to show a 3D view of an object, while orthogon...read more

Q1. Implementation of gd&t
Ans. 
GD&T is a system for defining and communicating engineering tolerances.
• GD&T stands for Geometric Dimensioning and Tolerancing

• It is used to define the allowable variations in form, size, and orientation of part features

• GD&T symbols are used on engineering drawings to specify the desired tolerances

• Proper implementation of GD&T can improve the quality and manufacturability of a design

Q2. Advantage gd&t and what is bonus tolerance
Ans. 
GD&T provides precise communication of design requirements, while bonus tolerance allows for additional variation beyond basic tolerances.
• GD&T (Geometric Dimensioning and Tolerancing) ensures clear and precise communication of design requirements

• It allows for more detailed control over form, orientation, location, and profile of features

• Bonus tolerance is an additional tolerance that can be applied to a feature beyond ...read more

Q3. Types of fits and advantages
Ans. 
Types of fits include clearance fit, interference fit, and transition fit, each offering different advantages.
• Clearance fit: allows for easy assembly and disassembly, used in applications where relative motion is required (e.g. sliding fits)

• Interference fit: provides a tight connection with no relative movement, used in applications where rigidity is important (e.g. press fits)

• Transition fit: offers a compromise betwee...read more

Q4. Expalain spring back effect in details
Ans. 
Spring back effect is the tendency of a material to return to its original shape after being deformed.
• Spring back effect occurs in materials like metals, plastics, and composites.

• It is caused by the release of internal stresses that were introduced during the forming process.

• Factors affecting spring back include material properties, forming process, and tooling design.

• Examples include metal sheets returning to their or

Q1. Storage class in c
Ans. 
Storage classes in C define the scope and lifetime of variables.
• There are 4 storage classes in C: auto, register, static, and extern.

• Auto variables are stored in memory and have local scope.

• Register variables are stored in CPU registers for faster access.

• Static variables retain their value between function calls.

• Extern variables are declared outside of any function and can be accessed by other files.
