1. Find weight and COG of an irrrgular shape. Unit weight of member was given. 2. Calculate force required for COG shift. W load was applied at center of rectangle and we had to calculate forces at all four corners to shift the cog. 3. SFD , BMD and free body diagram of a portal fixed at one end and other end was free. Load p was applied at length L cantilever from from middle of portal.

Interview questions for Structural Engineer

For irregular shape, find volume and multiply by unit weight to get weight. Divide moment of each part by total weight to get COG.
To calculate force required for COG shift, use moment equation. Sum of moments about any point should be equal to zero.
For SFD and BMD, use equations of equilibrium and moment. Draw free body diagram to show all forces acting on the portal.
Understand basic concepts of structural engineering such as moment, shear force, equilibrium, and free body diagrams.
Practice solving problems related to weight and COG calculations, moment equations, and SFD/BMD analysis.
Familiarize yourself with common types of structures such as beams, trusses, and frames.
Be prepared to explain your thought process and show your work during the interview.
