✅A Simply Supported Beam: 📌Definition: Structural element supported at both ends, free to rotate and deflect vertically under load. 📌Support Conditions: Rests on two points (rollers or pins). 📌Behavior under Load: Bends and experiences shear along its length, deflects downward with max deflection typically at center. 📌Equilibrium: Sum of vertical forces and moments equals zero. 📌Applications: Construction, bridges, engineering structures with moderate spans. 📌Mathematical Analysis: Statics
