B. The strut in the figure (green bar) has a mass of 45 kg. Calculate the tension in the blue cable and the x and y components of the force the hinge exerts on the strut. Step 1: Draw all the forces acting on the strut. Identify which forces are known and which are unknown (on diagram). Important: For the contact between the strut and the hinge, represent the x and y components of force the hinge exerts on the strut Fan?e? and Fe Which direction do they have to go based on the other forces? . Step 2: Based on the knowns and unknowns, choose a point of rotation for which to write = 0 which will eliminate all but one unknown. T Step 3: Use F 30 net T Strut 45 Hinge 225 kg Write that equation and solve for the unknown. Important: First, find the angle between the blue cable and the strut. Use geometry in the triangle that has this angle. = 0 and "net,? Fnet? = 0 to solve for any other unknown forces. Important: Find the angle that the cable makes with the horizontal direction. This is a different angle than the one you used above. You will need this angle to find the x component of the force in the cable. B. The strut in the figure (green bar) has a mass of 45 kg.
