The cable supports three vertical loads. The area of the cable is 0.1 ft2. The elastic modulus of the cable is 200,000 kips/ft2.
Determine the reaction forces and the maximum tension in the cable.
The model has 5 joints and 4 cable elements. A small tensile force
is specified as prestress force to give initial stiffness to the cable.
Nonlinear static analysis is performed using one (1) load step and maximum of 10 iterations.
The tension in the cable varies from 17.9 kips (element # 2) to 24.7 kips (element # 4).
