For a cantilever beam of length L with point load P at free end: 
ABM max at FIXED end = PL; SF constant = P along length
BRandom
CBM zero
DBM max at free end = PL
Answer & Solution
Correct answer: A. BM max at FIXED end = PL; SF constant = P along length
Cantilever with end load: SF = +P along beam length (constant). BM = -P × x at distance x from fixed end (linear, max at fixed end = PL, magnitude). Free end: SF and BM both zero (beyond load point). Max deflection at free end = PL³/(3EI).
