12 Derivation of Equilibrium Conditions for Support Reactions | Point Load at Mid-Span

Описание: In this lecture, we derive the equilibrium conditions used to determine support reactions for a simply supported beam carrying a point load at its mid-span. This topic is a fundamental concept in Engineering Mechanics, essential for understanding how structures maintain balance under various loading conditions.
What You’ll Learn:
Concept of equilibrium in rigid bodies
Derivation of support reactions using static equilibrium equations
Application of ΣFx = 0, ΣFy = 0, and ΣM = 0
Symmetrical loading and equal reaction distribution
Step-by-step example of a beam under point load
🏗️ Ideal for:
Engineering students, diploma learners, and anyone preparing for mechanics or civil engineering exams.
