Lazer Ken It Services Assistant Engineer Interview Questions, Process, and Tips

Q1. How to find the Reactions
Ans. 
Reactions can be found by analyzing the external forces and moments acting on a structure.
• Calculate the sum of forces in the x, y, and z directions to find the reaction forces at supports

• Analyze the moments around different points to determine the reaction moments

• Consider the equilibrium of the structure to ensure all forces and moments are balanced

Q2. What is Steel Structures
Ans. 
Steel structures are structures made primarily of steel components, known for their strength, durability, and versatility.
• Steel structures are commonly used in construction for buildings, bridges, and other infrastructure.

• They are known for their high strength-to-weight ratio, allowing for lighter and more efficient designs.

• Steel structures can be prefabricated off-site and assembled on-site, speeding up construction t...read more

Q3. How to define the moment and shear connection s
Ans. 
Moment and shear connections are used in structural engineering to transfer forces between members.
• Moment connections transfer bending forces between beams and columns

• Shear connections transfer shear forces between beams and columns

• Moment connections can be achieved through welding, bolting, or a combination of both

• Shear connections typically involve bolts or welds to transfer the shear forces

Q1. What is Retaining wall
Ans. 
A retaining wall is a structure designed to hold back soil or other materials to prevent erosion or collapse.
• Retaining walls are commonly used in landscaping to create terraces or level areas on sloped land.

• They can be made of various materials such as concrete, stone, brick, or wood.

• Retaining walls can be either gravity walls, cantilever walls, sheet pile walls, or anchored walls.

• Proper drainage behind the retaining w...read more

Q2. Shear force and bending moment diagram
Ans. 
Shear force and bending moment diagrams are graphical representations of internal forces in a structural element.
• Shear force diagram shows the variation of shear force along the length of the beam.

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

• Shear force is the sum of all vertical forces acting on one side of a cut section of the beam.

• Bending moment is the sum of all moments ...read more

Q3. Load calculation in a framed structure
Ans. 
Load calculation in a framed structure involves determining the forces acting on the structure to ensure it can safely support the intended loads.
• Identify all the loads acting on the structure, including dead loads (permanent), live loads (temporary), and environmental loads (wind, snow, etc.)

• Calculate the total load on each structural element by summing up all the individual loads it must support

• Consider factors such ...read more
