Dear jj77 and Peter,


 


How are you? Could you please have a look?


 


1. The result of SMISC1 is 3.4165E5, is it too large for tension force? 


 


2. the result is not sensitive for lateral force only along Z axis?


 


3. The equation for calculation for initial strain, unit less  Y is young's modulus, F is pretension, A is section area?


 


 


 


 thanks for help!


 


 two cables are connected with beam (truss) for transmission line simulation.
