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
= 19i - 10j 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.
