The roof truss serves to support a crane rail which is attached to the bottom cord of the truss as shown. Determine the maximum live force (tension or compression) that can be developed in member CH, due to the crane load of 10 kips. Specify the position x of the load (A, B, C, D, or E). Assume the truss is supported at A by a pin and at E by a roller. Also assume that all members are pin- connected at the gusset plates.

Load on Structures

Civil engineers primarily deal with beams in their day-to-day applications. A beam is a structural member that resists shear loadings. There are various types of beams such as cantilever beam, simply supported beam, and over the hanging beam. All these beams have a different end and loading conditions.
