alleryStart learning →Max deflection at center of simply-supported beam with central P:
APL/4
BPL³/(48EI)
CPL³/(48EI)
DwL⁴/(384EI)
Answer & Solution
Correct answer: B. PL³/(48EI)
**SSB central P:** δ_max at midspan = PL³/(48EI).
Standard formulas for various load cases: SSB UDL: 5wL⁴/(384EI).
**Cantilever end P:** PL³/(3EI).
**Cantilever UDL:** wL⁴/(8EI). EI = flexural rigidity.
