GE Edison Engineer Interview Questions, Process, and Tips

Al and Cu have different stress strain diagrams due to their different material properties.

• Al has a higher yield strength and ultimate tensile strength than Cu.

• Cu has a higher ductility than Al.

• Al has a more linear stress strain curve than Cu.

• Cu exhibits necking before fracture, while Al does not.

• The modulus of elasticity for Al is higher than Cu.

Ductility is the ability of a material to deform under tensile stress. Strain hardening is the increase in strength of a material due to plastic deformation.

• Ductility allows a material to be drawn into a wire or hammered into a thin sheet without breaking.

• Strain hardening occurs when a material is deformed beyond its elastic limit, causing dislocations in the crystal structure.

• Examples of ductile materials include copp...read more

Axial compressor is a key component in gas turbine engines that compresses air before combustion.

• Axial compressor consists of multiple stages of rotating blades and stationary vanes.

• Each stage compresses the air and increases its pressure.

• The compressed air is then mixed with fuel and ignited in the combustion chamber.

• The hot gases produced by combustion expand and drive the turbine, which in turn drives the compressor...read more

Principle stress and strain are the maximum and minimum stresses/strains experienced by an object in a given direction.

• Principle stress is the maximum stress experienced by an object in a given direction.

• Principle strain is the maximum strain experienced by an object in a given direction.

• They are important in determining the strength and failure of materials.

• For example, in a beam under bending, the maximum stress occu...read more

Natural frequency of a beam refers to the frequency at which the beam vibrates when disturbed from its equilibrium position.

• Natural frequency is determined by the material properties and geometry of the beam.

• It is important to consider natural frequency when designing structures to avoid resonance.

• The formula for natural frequency is f = (1/2π) * √(k/m), where k is the stiffness and m is the mass of the beam.

• Example: A...read more

Strength of materials refers to the ability of a material to withstand external forces without breaking or deforming.

• It is important in engineering design to ensure that materials used can withstand the expected loads and stresses.

• Factors that affect strength of materials include material composition, shape, and size.

• Testing methods such as tensile testing and compression testing are used to determine the strength of m...read more

Sorry, I cannot answer this question without knowing the series.

• Without knowing the series, it is impossible to predict the next few numbers.

• The series could follow any pattern or rule, making it unpredictable without more information.

• It is important to have all the necessary data before attempting to make predictions.

Use Singular Value Decomposition (SVD) to reduce matrix size while preserving important information.

• SVD breaks down a matrix into its constituent parts, allowing for the removal of less important information.

• The resulting smaller matrix can be used to approximate the original matrix with minimal loss of important information.

• This technique is commonly used in image compression and data analysis.

• Example: A 1000x1000 mat...read more

The expression of lift over air fail is derived using Bernoulli's principle and the equation for lift force.

• Lift force is equal to the product of air density, velocity squared, wing area, and lift coefficient.

• Airfoil shape and angle of attack affect lift coefficient.

• Bernoulli's principle states that as air velocity increases, air pressure decreases.

• The pressure difference between the top and bottom of a wing creates li...read more
