Re: Limit stop in Piping stress analysis

Dear Kaustubh

Could this method of multiple stop/restraint be arranged with springs? It reminds me of steam engines on rails. Without springs, only three wheels can be in contact with the rails, as a three legged stool. By use of springs (and rocker arms) many steam engines could drive through eight wheels. Surely there must be a way of restraint by proportional loading. What do you think?

Cheers
