Univlabs Interview Questions and Answers

Factor of safety is a design parameter that accounts for uncertainties and variations in materials, loads, and other factors to ensure the safety of a structure or component.

• Factor of safety is the ratio of the maximum stress a material can withstand to the maximum stress it is subjected to in a given application.

• It is used to prevent failure due to unexpected conditions such as variations in material properties, manufacturing defects, or higher than expected loads.

• For exampl...read more

Yield point is the stress at which a material begins to deform plastically.

• Yield point is the point on a stress-strain curve where the material transitions from elastic to plastic deformation.

• It is the stress level at which the material no longer returns to its original shape after the stress is removed.

• Yield point is an important factor in determining the strength and ductility of a material.

• Example: Steel has a well-defined yield point, while some materials like aluminum ex...read more

GD&T stands for Geometric Dimensioning and Tolerancing, a system for defining and communicating engineering tolerances.

• GD&T is a symbolic language used on engineering drawings to specify the allowable variations in form, size, and orientation of features.

• It helps ensure that parts fit together properly and function as intended.

• GD&T uses symbols such as concentricity, flatness, perpendicularity, and position to communicate design requirements.

• It is commonly used in industries ...read more

A stress-strain diagram shows the relationship between stress and strain in a material.

• It typically consists of a linear elastic region, a yield point, and a plastic deformation region.

• The slope of the linear region is the material's Young's Modulus.

• The yield point is where the material begins to deform plastically.

• The ultimate tensile strength is the maximum stress the material can withstand.

• The area under the curve represents the material's toughness.

Deadlock is a situation in which two or more competing actions are each waiting for the other to finish, preventing any of them from completing.

• Occurs in multitasking environments

• Caused by resource contention

• Can be resolved using techniques like deadlock prevention, deadlock avoidance, and deadlock detection

• Example: Process A holds Resource X and waits for Resource Y, while Process B holds Resource Y and waits for Resource X

Enum is used to define a set of named constants while struct is used to define a collection of variables of different data types.

• Enum is used to define a set of named constants, while struct is used to define a collection of variables of different data types.

• Enum values are typically integers, while struct members can be of any data type.

• Enums are used when you have a fixed set of values that won't change, while structs are used to group related variables together.

• Example: en...read more

Different function call methods include pass by value, pass by reference, and pass by pointer.

• Pass by value: Copies the value of the actual parameter into the formal parameter of the function.

• Pass by reference: Passes a reference to the memory location of the actual parameter.

• Pass by pointer: Passes the memory address of the actual parameter.

Moral motivation is driven by personal values and beliefs, while monetary motivation is driven by financial incentives.

• Moral motivation is based on doing what is right or ethical, regardless of financial gain.

• Monetary motivation involves being driven by financial rewards or incentives.

• Some individuals may prioritize moral motivation over monetary motivation, while others may prioritize financial gain.

• Examples: A person may choose to work for a non-profit organization out of a...read more
