Bonfiglioli Transmissions Private Limited R&D Design Engineer Interview Questions and Answers

Q1. GD & T symbols and it's uses
Ans. 
GD&T symbols are used in engineering to communicate design specifications and tolerances.
• GD&T symbols are used to specify geometric dimensions and tolerances on engineering drawings.

• They help ensure that parts are manufactured to the correct dimensions and fit together properly.

• Examples of GD&T symbols include concentricity, perpendicularity, and flatness.

• GD&T symbols are often used in conjunction with traditional dime

Q2. Stress strain and it's curve heat treatment process
Ans. 
Stress-strain curve is a graphical representation of the relationship between stress and strain in a material during a mechanical test.
• Stress-strain curve shows how a material deforms under load.

• It consists of elastic, plastic, and fracture regions.

• Heat treatment process involves heating and cooling a material to alter its properties.

• Heat treatment can change the microstructure of a material, affecting its mechanical p...read more

Q1. How many constrataunts you use to constraint a model in solid work
Ans. 
In SolidWorks, constraints are used to define relationships between different components in a model. The number of constraints needed can vary depending on the complexity of the model.
• The number of constraints required depends on the number of components in the model and the desired relationships between them.

• Common types of constraints include coincident, parallel, perpendicular, tangent, concentric, and distance cons...read more

Q1. What is Bernoulli principle?
Ans. 
Bernoulli principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.
• States that as the speed of a fluid increases, its pressure decreases

• Used to explain lift in airplane wings

• Applies to various fluid dynamics situations such as flow through pipes

Q2. What is stress and how it can be measured?
Ans. 
Stress is a force acting on a material that causes deformation. It can be measured using techniques like strain gauges and load cells.
• Stress is a measure of the internal forces within a material resisting deformation.

• It is typically measured in units of force per unit area, such as Pascals or pounds per square inch.

• Common methods of measuring stress include strain gauges, load cells, and extensometers.

• Stress can be cat...read more
