Each of the three members, AB, AC, and AD, of the tripod in Fig. P6–22 is secured by ball-and-socket connections and each is capable of exerting ten- sion or compression. The turnbuckle in wire AE is tightened so that the wire tension is 4080 lb. Determine the axial force in each member. Neglect the weights of the members.

A 20.0-kg floodlight in a park is supported at the end of a horizontal beam of negligible mass that is hinged to a pole as shown in the figure below. A cable at an angle of 30.0 degrees with the beam helps support the light. (a) Draw a force diagram for the beam. By computing torques about an axis at the hinge at the lefthand end of the beam, find (b) the tension in the cable, (c) the horizontal component of the force exerted by the pole on the beam, and (d) the vertical component of this force. Now solve the same problem from the force diagram from part (a) by computing torques around the junction between the cable and the beam at the right-hand end of the beam. Find (e) the vertical component of the force exerted by the pole on the beam, (f) the tension in the cable, and (g) the horizontal component of the force exerted by the pole on the beam. (h) Compare the solution to parts (b) through (d) with the solution to parts (e) through (g). Is either solution more accurate?
The light boom AB is attached to a vertical wall by a ball and socket joint at A and supported by two cables at B. A force P is applied at B where P = 17i - 11j kN.Note that the reaction force at A acts along the boom because it is a two-force member.

A 50 kg pole extends up a wall, making a 60° angle with the wall. The pole is supported by acable attached 3/4 of the way along the pole. This support cable is perpendicular to the wall.A 10 kg sign hangs from the end of the pole. The pole’s center of mass is 1/3 of the way fromthe wall to the end of the pole. (a) What is the tension in the cable?(b) What are the x and y components of the force the wall exerts on the pole?You must include an extended free body diagram showing all forces acting on the pole. Labelthe location on the pole you will use a reference for measuring distances (the “axis of rotation”) at the point where the pole touches the wall. Thank you!
