Please by Section Analysis:  Use the method of sections to find the true magnitude and direction in bar DB of the truss. Hint Joint C is in equilibrium).                                                 (B to D is not zero)

Find the magnitude of the force exerted on bolt A, given:P = 100 lb, L1 = 1.4 in, L2 = 5.4 in, L3 = 12 in, L4 = 0.4 in, L5 = 1 in

As shown, an L-shaped bar is supported by a pin at joint A. The bar's dimensions are aaa = 620 mmmm and bbb = 400 mmmm , and the bar is subjected to a force with magnitude FFF = 5.05 kNkN at joint B. Ignoring the bar's weight, find the actual orientation of the applied force. What is the value of the angle θθtheta?
