For cantilever beam with UDL w along entire length L:
ARandom
BBM max = wL²/2 at fixed end
CBM = 0
DBM at free end = wL²/2
Answer & Solution
Correct answer: B. BM max = wL²/2 at fixed end
**Cantilever UDL:** at distance x from fixed end (where total length L), shear = w(L-x), bending moment = w(L-x)²/2. Both max at fixed end: BM_max = wL²/2 (negative or 'hogging'), SF_max = wL.
Max deflection at free end = wL⁴/(8EI).
