FOX Solutions Design Engineer Interview Questions and Answers

Q1. What is the casting solidification time?
Ans. 
Casting solidification time is the duration it takes for molten metal to solidify in a casting process.
• Casting solidification time depends on factors like material type, mold temperature, and casting geometry.

• Higher pouring temperatures generally result in shorter solidification times.

• Thicker sections of the casting will take longer to solidify compared to thinner sections.

• Aluminum alloys typically have shorter solidif

Q3. What are the Casting design consideration?
Ans. 
Casting design considerations include material selection, part geometry, draft angles, surface finish, and shrinkage.
• Material selection is crucial for the desired properties and performance of the final part.

• Part geometry should be designed to minimize stress concentrations and ensure proper flow of molten metal.

• Draft angles are necessary for easy removal of the part from the mold.

• Surface finish requirements should be ...read more

Q2. Flywheel used in a engine
Ans. 
A flywheel is a mechanical device used in engines to store rotational energy and smooth out fluctuations in engine speed.
• Flywheels are typically made of steel or aluminum and are attached to the engine's crankshaft.

• They store energy during the power stroke and release it during the compression stroke to keep the engine running smoothly.

• Flywheels are also used in hybrid vehicles to store energy from regenerative braking...read more

Q3. Used of flywheel, crankcase, AVM pre filter
Ans. 
Flywheel, crankcase, and AVM pre filter are components used in internal combustion engines.
• Flywheel stores rotational energy and helps maintain engine speed during power strokes.

• Crankcase houses the crankshaft and other engine components.

• AVM pre filter is used to remove larger particles from the air before it enters the engine.

• These components are essential for the proper functioning of internal combustion engines.

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
