L&T Water & Effluent Treatment Post Graduate Engineer Trainee Interview Questions and Answers

Q1. How to find yield strength of 8mm dia steel of 550 grade?
Ans. 
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

Q4. Draw shear force and bending moment diagrams
Ans. 
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
