  1. Statics and Basic Mechanics What you forgot from basic physics

  2. Forces: In The General Vector Quantities Magnitude and Direction Statics Balanced Forces = No Acceleration

  3. External Forces: Normal

  4. External Forces: Moments

  5. Forces: Compression Aspect Ratio Matters

  6. Forces: Tension Aspect Ratio Doesn’t Matter

  7. Forces: Bending

  8. Carrying Forces (loads) Tension

  9. Carrying Forces (loads) Smooth Surfaces

  10. Carrying Forces (loads) Rough Surfaces

  11. Carrying Forces (loads) Roller Supports

  12. Carrying Forces (loads) Sliding Joints

  13. Carrying Forces (loads) Pin Connection

  14. Carrying Forces (loads) Fixed Support

  15. The Basis of Statics F=Ma=0 SF=Ma=0 SM=Ma=0

  16. An Example: A Pulley

  17. Examining an Object/Building/Robot: 1) How is the weight of the thing supported? 2) How does it change if it is under motion? 3) Other interesting aspects of the device? Draw a free body diagram of part 1
