ME221 Lecture 15 2 Chapter 6: Analysis of Structures The knowledge of internal forces is a fundamental requirement for true design The Structural elements are: Trusses Frames Machines

ME221 Lecture 15 3 Trusses Composed of slender straight pieces connected together by frictionless pins where all the loads (no moments) are applied. Each member will act as a two-force member (either in tension or compression). All the forces acting on a truss member are axial.

ME221 Lecture 15 4 Frames Are designed to support, prevent or transmit loads (forces, no moments). At least one member is not a two-force member. Machines Are designed to transmit force, motion or energy (forces and moments). Will always have at least one member with multiple forces.

ME221 Lecture 15 5 Planar Trusses If the planar truss (2-D) is statically determinant, then the number of joints is related to the number of reactions and internal members by : 2j = m + r j = number of joints m = number of internal members r = number of reactions
