Tejas Networks Mechanical Engineer Interview Questions and Answers

Bending moment is a measure of the bending effect on a beam or structural element.

• Bending moment is the algebraic sum of moments about the neutral axis of a section of a beam or structural element.

• It is caused by external forces acting on the beam, resulting in a bending or flexural deformation.

• Bending moment is calculated using the formula: M = F * d, where M is the bending moment, F is the force applied, and d is the...read more

Strain is the deformation of a material under load, while stress is the force applied to a material per unit area.

• Strain is a measure of how much a material deforms under stress.

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

• Strain is a dimensionless quantity, while stress is measured in units of force per unit area (such as N/m^2 or Pa).

• Strain can be either tensile (stretching) or compressive (squeezing), whi...read more

Heat treatment is a process used to alter the physical and sometimes chemical properties of a material through heating and cooling.

• Heat treatment involves heating a material to a specific temperature, holding it at that temperature for a certain amount of time, and then cooling it at a controlled rate.

• The purpose of heat treatment is to improve the material's hardness, strength, toughness, ductility, and other properti...read more

Structures are rigid bodies that support loads, while links are flexible elements that connect structures.

• Structures are typically made of rigid materials like steel or concrete

• Links are often made of flexible materials like cables or chains

• Structures provide support and stability to a system

• Links allow for movement or flexibility within a system

• Example: A bridge is a structure that supports loads, while the cables con
