Given the beam shown, what is the internal bending moment at the left end? (HINT: The internal bending moment at an end reaction of a beam is equal in magnitude to the moment reaction at that location. Cut the beam an infinitesimal distance from the reaction such that ONLY the reactions,
V
, and
M
are included in your free-body diagram.) * (2.5 Points) 10016
