Unformatted text preview: 4. 101 A 1.2 X 2.44m sheet efpiwend having a mass of 17 kg has been temporarily placed among three pipe supports. The lewer edge of the sheet rests on small collars A and B and its upper edge leans against pipe C. N e- glecting friction at all surfaces, determine the reactions at A, B, and C. 4.102 200 X EODAmrn square plate she-em has a mass at 25 kg and is supported by three vertical wires. Determine the tensien in each wire. 4.105 Two steel pipes AB and BC: each having a weight per unit length of 5 lhfft, are welded together at B and are supported by three wires. Know— ing that e = 1.25 ft, determine the tension in each wire. Fig. P4.105 4.115 The 18—1} pole ABC is acted upon by a Elli—1b force as shown. The pole is held by a ball-and—soeket joint at A and by two cables BD and BE. For a = 9 ft. determine the tension in each cable and the reaction at A. 5’ .At Fig. P4.116 ...
