A cable is loaded by means of a uniform load. Isto resulta numa forma deformada de um segmento circular. Determine the equilibrium force of the cable to obtain the given sag of the cable. The add-on module RF-FORM-FINDING is used for this purpose. Elastic deformations are neglected both in RF-FORM-FINDING and in the analytical solution; self-weight is also neglected in this example.
Entre dois pilares, encontra-se suspenso um cabo muito resistente. Determine the equilibrium shape of the cable (the catenary), consider the gravitational acceleration, and neglect the stiffness of the cable. Verify the position of the cable at the given test points.
A truss structure consists of three rods (one steel and two copper) joined by a rigid member. The structure is loaded by a concentrated force and a temperature difference. Determine a flecha total da estrutura, sem considerar o peso próprio.
A structure made of I-profile trusses is supported on both ends by spring sliding supports and loaded by transversal forces. O peso próprio não é considerado neste exemplo. Determine the deflection of the structure, the bending moment, the normal force in the given test points, and the horizontal deflection of the spring supports.
