Support Definition and 385 Threads

Technical support (often shortened to tech support) refers to services that entities provide to users of technology products or services. In general, technical support provides help regarding specific problems with a product or service, rather than providing training, provision or customization of the product, or other support services. Most companies offer technical support for the services or products they sell, either included in the cost or for an additional fee. Technical support may be delivered by phone, e-mail, live support software, live chat or website, or other tools where users can log an incident. Larger organizations frequently have internal technical support available to their staff for computer-related problems. The Internet can also be a good source for freely available tech support, where experienced users help users find solutions to their problems. In addition, some fee-based service companies charge for premium technical support services.

    Using centrifugal force to support pressure vessels

    If the walls of a submarine were supported by fast-spinning rings, using centrifugal force to prevent collapse or buckling, would this be viable engineering? I am assuming that the rings would be magnetically suspended to eliminate friction. This also seems like a self-stabilizing system with...

    Why do small waveguides support less modes than larger ones?

    I've taken several courses on Electromagnetics and Waveguide. It has become common sense to me that small waveguides support less modes than larger ones. I've also learned the graphical method to calculate the number of modes in a 3-layer slab waveguide. What I don't get is why small...
