Tata Technologies Senior Engineer Interview Questions and Answers

Routing harness in NX involves using tools for efficient design, layout, and validation of electrical harness systems.

• Utilize the NX Electrical Routing module for creating harness designs.

• Define the harness structure by specifying connectors, wires, and components.

• Use the 'Route' command to create paths for wires, ensuring minimal bends and optimal space utilization.

• Incorporate design rules to check for clearance and interference during the routing process.

• Validate the harnes...read more

I used MATLAB, ANSYS, and SolidWorks for my MTech thesis work.

• MATLAB for data analysis

• ANSYS for simulations

• SolidWorks for design and modeling

Stress is the internal force per unit area within a material, while pressure is the external force per unit area exerted on a surface.

• Stress is a measure of the internal forces within a material, while pressure is a measure of the external forces acting on a surface.

• Stress is a scalar quantity, while pressure is a vector quantity.

• Stress is measured in units of force per unit area, while pressure is measured in units of force per unit area.

• Examples of stress include tension, c...read more

Ductile materials exhibit large deformation before failure, while brittle materials fail suddenly with little deformation.

• Ductile materials have a gradual slope on the stress-strain curve, showing plastic deformation before fracture.

• Brittle materials have a steep slope on the stress-strain curve, showing little to no plastic deformation before fracture.

• Examples of ductile materials include steel and aluminum, while examples of brittle materials include ceramics and glass.

Stress is the force applied to a material, while strain is the resulting deformation or change in shape.

• Stress is the force applied per unit area on a material.

• Strain is the measure of deformation or change in shape of a material.

• Stress and strain are related by the material's modulus of elasticity.

• Example: When a rubber band is stretched (strain), the force applied to it is the stress.
