10+ Engineering Analyst Interview Questions and Answers

Fasteners with high axial stiffness should be used for providing buckling stability to shell.

• Fasteners with high axial stiffness like bolts, screws, or rivets should be used.

• The fasteners should be placed at regular intervals along the shell.

• The fasteners should be tightened to a specific torque to ensure stability.

Isotropic hardening refers to the change in yield stress due to plastic deformation, while kinematic hardening refers to the change in yield stress due to cyclic loading. Translation of yield surface refers to the shift of the yield surface in stress space.

• Isotropic hardening is associated with the change in yield stress due to plastic deformation.

• Kinematic hardening is associated with the change in yield stress due to cyclic loading.

• Translation of yield surface refers to the...read more

Shell elements have rotational DOF to capture bending and twisting behavior.

• Rotational DOF allow shell elements to model the bending and twisting behavior of structures.

• Without rotational DOF, shell elements would only be able to capture translational movements.

• Rotational DOF enable accurate representation of complex geometries and loading conditions.

• For example, in a thin-walled structure like an aircraft wing, rotational DOF are crucial to capture the bending and twisting i...read more

To estimate the volume of paint required for a room, measure the dimensions of the room and calculate the surface area of the walls and ceiling.

• Measure the length, width, and height of the room

• Calculate the surface area of the walls by multiplying the height by the sum of the lengths of all the walls

• Calculate the surface area of the ceiling by multiplying the length and width of the room

• Add the surface area of the walls and ceiling to get the total surface area

• Determine the c...read more

Colour coding is a method of organizing and identifying items based on specific colours assigned to different categories or characteristics.

• Used in various industries for organization and identification purposes

• Commonly used in electronics for identifying components (e.g. resistors, capacitors)

• Helps improve efficiency and reduce errors in tasks that involve sorting or categorizing items

A network is a collection of computers, servers, mainframes, network devices, and other devices connected to one another to share data and resources.

• Networks can be wired or wireless

• They can be local (LAN), wide area (WAN), or global (Internet)

• Networks use protocols like TCP/IP to facilitate communication

• Examples include Ethernet, Wi-Fi, and cellular networks

BSOD stands for Blue Screen of Death, a Windows operating system error screen displayed when a system encounters a critical error.

• BSOD is a screen displayed by Microsoft Windows when the system encounters a critical error that it cannot recover from.

• It usually includes an error code and information about the error that caused the system to crash.

• BSOD can be caused by hardware failures, software issues, or driver problems.

• Commonly known as the 'Blue Screen of Death' due to the...read more

RAM stands for Random Access Memory, a type of computer memory that can be accessed randomly; it is volatile and temporary.

• RAM is a type of computer memory that stores data and machine code currently being used by the CPU.

• It is volatile, meaning it loses its data when the computer is turned off.

• RAM is faster to read from and write to than other types of storage like hard drives.

• Examples of RAM include DDR4, DDR3, and LPDDR4.

The question asks to draw the Free Body Diagram (FBD) of a given structure.

• A Free Body Diagram (FBD) is a visual representation of the forces acting on an object or structure.

• It helps in analyzing the equilibrium and determining the internal forces within the structure.

• The FBD should include all external forces acting on the structure, such as applied loads, reactions, and support conditions.

• Each force should be represented by a vector with appropriate magnitude and direction...read more

Entity Framework (EF) has a lifetime scope tied to the DbContext instance.

• Lifetime scope of EF is tied to the DbContext instance

• DbContext should be short-lived and disposed of after use

• DbContext should not be shared across multiple threads

• DbContext should be created and disposed of within a using block
