The light boom AB is attached to a vertical wall by a ball
and socket joint at A and supported by two cables at B. A
force P is applied at B where P = 20i - 9j kN.Note that the
reaction force at A acts along the boom because it is a
two-force member. Calculate the magnitude of the
reaction force at A in kN.
