Principal stresses and strains- Top Strength of materials solved problems MCQ l LNT l TATA |SOM

Описание: This video consists of the top most important questions asked in Civil engineering competitive exams and interviews for GATE, ESE, UPSC, SSC, JE,AE. This video focuses on concrete technology and reinforced cement concrete and strength of materials - the topic where most questions come from. QUESTION on Shear force diagram and bending moment diagram is given here. This also covers bending equation questions, principal stresses and strains and shear forces.

This covers the basic knowledge needed for any site engineer when going for an interview.
