Resolving Forces in 2D and 3D

    Cards (5)

    • Transmissibility
      The application of a force anywhere along its line of action
    • Resolving forces

      Allows for easier understanding of a situation
    • Steps to resolving forces
      1. Sketch a free-body diagram
      2. Objective - find the force needed and its orientation
      3. List variables in the question
      4. Equations - create and use equations
      5. Maths - write out what you know in mathematical terms
    • Finding a force vector when the angle is unknown, but you have the coordinates in 2D space
      Use the length formula
    • Checking/justifying work
      Use pythagoras to check
