Please solve these question in details and fully explaination. Thanks so much in advance.

The boom is intended to support two vertical loads, F1 and F2. If the cable CB can sustain a maximum tension of 1410 N before it fails. Consider L1 = 1.9 m, L2 = 1.1 m, and d = 20 degrees. If F1 = 2F2, 3) Determine the magnitude of the critical load F1 in kilonewtons. b) Determine the magnitude of the critical load F2 in kilonewtons. c) Determine the magnitude of the horizontal and vertical component of the maximum reaction at pin A in kilonewtons
