The 6-m pole ABC is acted upon by a 520-N force, P, as shown in the figure. The pole is held by a ball-and-socket joint at A and by two cables BD and BE.
For a=3m, determine the tension in each cable and the reaction at A. (Include a minus sign if necessary.)
The tension in cable BD is
N.
The tension in cable BE is _(()_())_(_()) N.
The reaction at A_(_())_(_()) N
