Answer 1

hey dude
 The bending moment at any section in a beam is defined as the total moments acting on the section due to loads/ moments applied on any one side of the section.

In a cantilever beam, the load acting on the right hand side of the section at the free end is always 0 irrespectively of the load acting on the beam because no span for placing loads is available on the right hand side of the section at the free end. Since the loads acting on the section are 0, the moments due to these loads are also 0.
