Hi tech help, L = 592.5 It doesnâ€™t matter what values are used for F or the angle or placement of the load F. The above parameters cannot be solved in Catenary+. When I try to enter x = 587.85 it errors with " 0 < x < 586.575 " Please help. I need to apply a point load and I need it to work! |
Hi Whilst the 'Catenary' calculation for x,y co-ordinates is iterative, it completes its calculation using only one iteration and is therefore able to resolve all unknowns very easily and accurately. The calculation method used in 'Catenary+', however, uses numerous (6) nested iterations and would therefore find it more difficult to achieve accurate results in extreme situations. CalQlata has therefore incorporated operational limits in order to ensure acceptable error margins for all successful calculations. Your calculation pull's a line 592.5 long between two points 591.2793846 apart which can be considered 'bar-tight' (see 3rd paragraph in the program's Technical Help) or very close to it. This is the reason why you have found an upper distance limit for 'x' of <586.575 for your calculation. This co-ordinate limit is artificially imposed by the program. CalQlata could provide you with a modified version of the program for your personal use but you would need to heed the following: I hope the above is of some help |
