Nagarjuna Construction Company Post Graduate Engineer Trainee Interview Questions, Process, and Tips

The yield strength of 8mm dia steel of 550 grade can be found using standard testing methods.

• Yield strength is the maximum stress a material can withstand without permanent deformation

• Standard testing methods like tensile testing can be used to determine the yield strength

• The 550 grade refers to the minimum yield strength of the steel

• Consulting the material's specification or conducting tests can provide the exact yiel

Bleeding and segregation are phenomena that occur in concrete during its placement and curing process.

• Bleeding is the process of water rising to the surface of freshly placed concrete due to the settlement of solid particles.

• Segregation refers to the separation of coarse aggregates from the rest of the concrete mix, resulting in an uneven distribution of materials.

• Bleeding can lead to a weakened surface layer and reduc...read more

The design mix ratios of concrete mixes vary depending on the specific requirements and applications.

• Design mix ratios are determined based on factors such as strength, workability, durability, and environmental conditions.

• Common design mix ratios include 1:2:4 (cement:sand:aggregate) for general construction, 1:1.5:3 for reinforced concrete, and 1:0.5:1 for high-strength concrete.

• Different types of concrete mixes, suc...read more

Shear force and bending moment diagrams are graphical representations of the internal forces and moments in a structural element.

• Shear force diagram shows the variation of shear force along the length of the element.

• Bending moment diagram shows the variation of bending moment along the length of the element.

• Shear force and bending moment diagrams are commonly used in structural analysis and design.

• These diagrams help e...read more
