We use vectors to mathematically model, or describe numerous physical quantities. In this course wewill use vectors to model forces, moments, and couples. If we want to work with forces, moments, andcouples we need to work with them the same way we work with vectors….x, y, z componentsMagnitude and direction (unit vector)We describe vectors‐‐‐GraphicallyAdd x components, add y components, etc.We add vectors‐‐‐Dot or scalar productsCross or vector productWe multiple vectors‐‐‐Vectors‐Forces, Couples, MomentsSunday, August 21, 20112:27 PMLecture 1 Page 1
