4. 1) For the frame structure shown below, the joints at points A, B, C, D and E are all pin connections. If force P1 = 420 lb and force P2 = 360 lb, determine the magnitude of the support reaction (in lb) at pin A. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point. Pi 60° B F 4 ft E D 3 ft -3 ft P2
