Unformatted text preview: Lecture 8 Notes courtesy of: Prof. Yoav Peles ENGR-1100 Introduction to Engineering Analysis Important Information! • Today we use Statics textbook again! Homework Assignment (from Statics textbook; due next class) • Problem 3-23 • Problem 3-26 Lecture Outline • Particle Equilibrium (3D) • Vector cross product Equilibrium of a particle • Large bodies or small bodies can be referred to as particles when the size and shape of the body have no effect on the response of the body to a system of forces. • The mass of the body can be assumed to be concentrated at a point and the shape can be neglected. • A necessary and sufficient condition for equilibrium: R = Σ F =0 Where Σ F is the sum of all forces acting on a particle. Equilibrium of a particle – 3D R = R x + R y + R z = = R x i + R y j + R z k = Σ F x i + Σ F y j + Σ F k k = 0 The equation can only be satisfied if: R x = R x i = Σ F x i =0 R y = R y j = Σ F y j =0 z z Example – P3-22 Struts AB and AC of Fig. P3-22 can transmit only axial tensile or Struts AB and AC of Fig....
