    Solution:

    (a) In order to identify the features of the loaded beam, some additional notations were added on the given figure, which will be used in the next calculations.
    The vertical reactions can be determined by writing the balance of forces and moments:
    - forces:
    ( 1)
    - moments (about the support A):
    ( 2)
    The last equation will give R2:
    ( 3)
    Numerically:
    ( 4)
    It follows from (1) that ( 5)
    Consequently, the bending moments at locations B and C will be:
    ...
