Analysis Type(s): Static, Stress Stiffening Analysis (ANTYPE = 0) Element Type(s): Tension-only or Compression-only Spar Elements (LINK10) Input Listing: vm31.dat Test Case The cable AE supports three vertical loads from the points indicated. For the equilibrium position shown, determine the horizontal Ax and vertical Ay reaction forces at point A and the maximum tension T in the cable. Figure 31.1 Hanging Load Problem Sketch Material Properties E = 20 x 106 ksi Geometric Properties Area of cable = 0.1 ft2 = 10 ft 1 = 5.56 ft 2 Loading F1 = 4 kips F2 = 6 kips = 5.83 ft Analysis Assumptions and Modeling Notes An iterative solution is required. A small initial strain (1 x 10-8) is input to give some initial stiffness to the cable. ANSYS Verification Manual .
