Q1. Explain stress, strain curve diagram with example?
Ans. 
Stress-strain curve shows relationship between stress and strain in a material under tension.
• Stress-strain curve is a graphical representation of how a material deforms under stress.

• It typically consists of a linear elastic region, a yield point, plastic deformation, and ultimate failure.

• Example: Steel has a high yield strength, so its stress-strain curve shows a steep initial slope.

• Example: Rubber has a low yield stre...read more

Q2. What is DOF? How many degrees of freedom from any object
Ans. 
DOF stands for Degrees of Freedom. It refers to the number of independent parameters that define the configuration of an object.
• DOF is the number of ways a rigid body can move in 3D space.

• For a rigid body in 3D space, there are 6 degrees of freedom - 3 translational and 3 rotational.

• Examples of DOF include linear motion along x, y, z axes and rotational motion around x, y, z axes.

Q1. Explain various GD&T
Ans. 
Geometric Dimensioning and Tolerancing (GD&T) is a system for defining and communicating engineering tolerances.
• GD&T is used to specify the allowable variations in form, size, and orientation of features on a part.

• It uses symbols, such as concentricity, flatness, and perpendicularity, to communicate the desired tolerances.

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

• Examples of GD&T symbo...read more

Q2. Explain DFM, DFS, DFA
Ans. 
DFM, DFS, and DFA stand for Design for Manufacturing, Design for Service, and Design for Assembly, respectively.
• DFM focuses on designing products that are easy and cost-effective to manufacture.

• DFS focuses on designing products that are easy to service and maintain.

• DFA focuses on designing products that are easy to assemble.

• Consideration of DFM, DFS, and DFA principles can lead to more efficient and cost-effective prod...read more

Q1. What is Bend Radius?
Ans. 
Bend Radius is the minimum radius a material can be bent without causing damage or deformation.
• Bend Radius is a measure of the flexibility of a material.

• It is important to consider the Bend Radius when designing parts or structures to ensure they can be bent without breaking.

• The Bend Radius is typically specified in the design or manufacturing specifications.

• For example, in sheet metal fabrication, the Bend Radius dete...read more

Q2. Why do we Provide Beeds on Sheet Metal Parts
Ans. 
Beads are provided on sheet metal parts to increase strength, stiffness, and rigidity.
• Beads help to prevent buckling or deformation of the sheet metal under load.

• They improve the overall structural integrity of the part.

• Beads can also enhance the aesthetic appearance of the part.

• They can be used to reinforce specific areas or create a desired shape.

• Examples of sheet metal parts with beads include automotive body panels
