10+ QuillBot Inc Interview Questions and Answers

Bending moment is the force that causes a beam to bend. Torque is the force that causes an object to rotate. Beams can be classified into different types based on their shape and support. Angle of projection is the angle at which an object is projected. Composite materials are made up of two or more materials with different properties.

• Bending moment is the product of force and distance from the force to the point of rotation.

• Torque is the product of force and the perpendicula...read more

Gas turbine works on Brayton cycle.

• Gas turbine works on Brayton cycle which is a thermodynamic cycle.

• It consists of four processes - isentropic compression, constant pressure heat addition, isentropic expansion, and constant pressure heat rejection.

• The working fluid in the cycle is air.

• Gas turbines are commonly used in power generation, aviation, and industrial applications.

The types of heat transfer are conduction, convection, and radiation.

• Conduction is the transfer of heat through direct contact between objects or substances.

• Convection is the transfer of heat through the movement of fluids or gases.

• Radiation is the transfer of heat through electromagnetic waves.

• Examples of conduction include touching a hot stove or holding a metal spoon in hot soup.

• Examples of convection include boiling water or using a fan to cool a room.

• Examples of radiatio...read more

Tuple is an immutable sequence type in Python that can store multiple values of different data types.

• Tuples are defined using parentheses () and separated by commas.

• Tuples can be accessed using indexing or slicing.

• Tuples are immutable, meaning their values cannot be changed once defined.

• Tuples are commonly used for returning multiple values from a function.

• Tuples can also be used as keys in dictionaries.

• Example: my_tuple = (1, 'hello', True)

• Accessing tuple values: my_tuple[0]...read more

The Brayton cycle is a thermodynamic cycle used in gas turbine engines.

• It consists of four processes: isentropic compression, constant pressure heat addition, isentropic expansion, and constant pressure heat rejection.

• It is used in gas turbine engines to produce power.

• The cycle is named after George Brayton, who developed the first commercial gas engine to use this cycle in 1872.

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

• It is an important concept in engineering and physics

• It is measured in terms of stress and strain

• Factors that affect strength of material include temperature, pressure, and composition

• Examples of materials with high strength include steel and titanium

• Testing methods for strength of material include tensile testing and compression testing

C++ is an extension of C with object-oriented programming features.

• C++ supports object-oriented programming while C does not.

• C++ has a richer set of data types and operators than C.

• C++ has better support for exception handling and templates than C.

• C++ allows function overloading while C does not.

• C++ has a standard library that includes many useful functions and classes.

• C++ is backward compatible with C code.

• C++ is generally considered more complex than C.

Y+ value is a parameter used in computational fluid dynamics to determine the accuracy of the simulation near solid boundaries.

• Y+ value is a dimensionless parameter that represents the ratio of the distance from a solid boundary to the first grid point to the viscous sublayer thickness.

• It is used to ensure that the simulation accurately captures the boundary layer flow near solid surfaces.

• A Y+ value of around 1 is typically considered ideal for most simulations.

• Y+ value is im...read more

Quality metrics for meshing refer to the criteria used to evaluate the accuracy and efficiency of mesh generation in computational simulations.

• Aspect ratio: measures the quality of elements based on their shape

• Skewness: evaluates the distortion of elements

• Orthogonality: assesses the angle between adjacent elements

• Convergence: determines the mesh resolution needed for accurate results

Isometric view is a 3D representation of an object with equal dimensions along three axes.

• Isometric view shows the object from a fixed angle, usually 45 degrees.

• All three dimensions of the object are shown in equal measure.

• It is commonly used in engineering and architecture for technical drawings.

• Isometric view is different from perspective view, which shows objects with foreshortening.

• Examples of isometric view can be seen in video games, such as Minecraft and SimCity.
