We use vectors to mathematically model, or describe numerous physical quantities. In this course we will use vectors to model forces, moments, and couples. If we want to work with forces, moments, and couples we need to work with them the same way we work with vectors…. x, y, z components Magnitude and direction (unit vector) We describe vectors ‐‐‐ Graphically Add x components, add y components, etc. We add vectors ‐‐‐ Dot or scalar products Cross or vector product We multiple vectors ‐‐‐ Vectors Forces, Couples, Moments Sunday, August 21, 2011 2:27 PM Lecture 1 Page 1
