Abstract: A building system, method and components are provided. A beam has two or more co-extensive planar lengthwise portions, each planar lengthwise portion defining a pitch of a different adjacent side of a roof. A connector assembly is provided for cooperatively connecting to the beam, where the connector assembly includes a support member, and one or more tabs extending radially from the support member. A plane of the tab corresponds to an angle of a hip or ridge or valley between respective different adjacent sides of the roof. The tab connects to the support member, and includes a connection receiving portion for connecting to the beam. The beam is cantilevered away from the connector assembly when cooperatively connected thereto.

Abstract: A modular rocket motor having a cylindrical housing with one end having an inwardly curved rim and the other end having internal threads. A heat-resistant plastic liner and a threaded nozzle cap are slidingly insertable with the cylindrical housing, with the threaded nozzle cap mating with the internal threads of the cylindrical housing. The motor is threaded into a rocket frame. A nozzle cap with liner attached thereto for a modular rocket motor that is colour coded to indicate the performance classification of the rocket motor.
