Question

The streetlight A is attached to the end of the horizontal boom ABO. The
light, which weighs 100 N, is subjected to a wind load of 20 N acting in the neg￾ative y-direction. The forces P and Q represent the tensions in the two cables that
are attached at point B. The resultant of the four forces shown is a force R acting
at point O. Determine the tensions P and Q and the force R.
