A turnbuckle, similar to that shown in Figure, is used to tension member AB of the truss. The coefficient of the static friction between the square threaded screws and the turnbuckle is μs = 0.5. The screws have a mean radius of 6 mm and a lead of 3 mm. If a torque of M = 10 N • m is applied to the turnbuckle, to draw the screws closer together, determine the force in each member of the truss. No external forces act on the truss.
