Mechanical Designer Interview Questions and Answers for Freshers

Various standards used in mechanical design include ASME, ISO, ANSI, and ASTM.

• ASME standards are used for pressure vessels and piping systems

• ISO standards are used for international standardization of mechanical design

• ANSI standards are used for dimensional and material specifications

• ASTM standards are used for materials testing and evaluation

3rd angle is a method of representing a 3D object in a 2D drawing by placing the object behind the viewing plane.

• In 3rd angle projection, the top view is placed above the front view and the right side view is placed to the right of the front view.

• Commonly used in engineering and technical drawings to accurately represent the object in 2D.

• Helps in visualizing the object from different perspectives without actually rotating it in space.

GD&T stands for Geometric Dimensioning and Tolerancing, a system used to define and communicate engineering tolerances.

• GD&T is a symbolic language used on engineering drawings to specify the allowable variation in form and size of features.

• It uses symbols, such as squares, circles, and triangles, to define the tolerance zones for features.

• GD&T helps ensure that parts fit together properly and function as intended.

• Examples of GD&T symbols include concentricity, flatness, perpe...read more

1st angle is a method of projection used in engineering drawings to represent a 3D object on a 2D plane.

• 1st angle projection involves placing the object in the first quadrant of a coordinate system.

• In 1st angle projection, the object is projected onto a plane located between the viewer and the object.

• Commonly used in Europe and Asia.

• Used in engineering drawings to accurately represent the object's dimensions and features.
