Statics:The Next Generation Mehta & Danielson Lecture Notes for Sections 6.1-6.3 2 SJTU 上 海 交 通 大 学 Introduction to Solid Mechanics -Vm211 APPLICATIONS Trusses are commonly used to support a roof. For a given truss geometry and load, how can we determine the forces in the truss members and select their sizes? A more challenging question is that for a given load, how can we design the trusses’ geometry to minimize cost? SJTU 上 海 交 通 大 学 Introduction to Solid Mechanics -Vm211 APPLICATIONS Trusses are also used in a variety of structures like cranes and the frames of aircraft or space stations. How can we design a light weight structure that will meet load, safety, and cost specifications? SJTU 上 海 交 通 大 学 Introduction to Solid Mechanics -Vm211 DEFINING A SIMPLE TRUSS (Section 5.1) A truss is a structure composed of slender members joined together at their end points. If a truss, along with the imposed load, lies in a single plane (as shown at the top right), then it is called a planar truss ....
