Koch Business Solutions Product Design Engineer Interview Questions and Answers

Q1. What is stress strain curve
Ans. 
Stress strain curve shows the relationship between stress (force applied) and strain (resulting deformation) in a material.
• It is a graphical representation of the behavior of a material under loading.

• The curve typically consists of elastic, plastic, and fracture regions.

• The slope of the curve in the elastic region is the material's Young's Modulus.

• The ultimate tensile strength and yield strength can be determined from ...read more

Q2. What is the difference between 2d and 3d
Ans. 
2D refers to two-dimensional objects or images that have length and width, while 3D refers to three-dimensional objects or images that have length, width, and depth.
• 2D objects are flat and have only length and width, like a piece of paper or a photograph.

• 3D objects have length, width, and depth, like a cube or a sphere.

• 2D images are typically represented on a plane, while 3D images can be viewed from multiple angles.

• 3D...read more

Q1. How can you define the Difference between a slope and a Gradient
Ans. 
A slope is the steepness of a surface while a gradient is the rate of change of a variable.
• Slope refers to the angle of inclination of a surface, while gradient refers to the change in elevation or value of a variable over a distance.

• Slope is measured in degrees or percentage, while gradient is measured in units of the variable per unit of distance.

• For example, the slope of a hill is 30 degrees, while the gradient of t...read more
