65) If a cantilever beam is subjected to a point load at its free end, then its bending moment diagram will look like

Answer is:

A right-angled triangle with zero bending moment at free end and maximum bending moment at fixed end

Explanation:

If a cantilever beam is subjected to a point load at its free end, then its bending moment diagram will look like a right-angled triangle with zero bending moment at free end and maximum bending moment at fixed end.
