EGR 251 : Statics

This course considers the effects of forces on rigid bodies in two and three dimensions. Students apply engineering concepts of force vectors, moments, and static equilibrium to solve engineering design problems. The course investigates techniques for structural analysis of beams, columns, mechanisms, trusses and shafts. Topics include friction, torsion, centroids, center of gravity, moment of inertia, and shear and moment diagrams. Three lecture hours per week. Fall

Prerequisites

  1. Define scalars, vectors, vector components and principles of static equilibrium.
  2. Differentiate between body forces, internal forces, external/applied forces, and reactions as supports.
  3. Analyze structures (trusses, beams and others) to find external reactions and internal forces using graphical techniques, summation of forces and moments, the dot product, and the cross product.
  4. Apply the concepts of moments and rotational equilibrium, static and dynamic friction to the analysis of the interaction of rigid bodies.
  5. Use the Method of Sections and Method of Joints to analyze trusses.
  6. Define the properties of a body (Center of Gravity, Centroid and Moment of Inertia) and apply them to the analysis of beams.
