Forces

Forces

1. Key properties of construction materials

   • Strength
   • Ductility
   • Density

2. Sresses caused by forces

   • Bending stress
   • Shear stress
   • Tensile stress
   • Compressive stress

3. What is a force?

   • Why do we need to calculate force?
     • Newtons second law of motion
       • f=ma
         • Explain the formula
     • Newtons 1st law of motion

4. Gravity

   • How does this impact us on earth?
   • Who discovered it, how do we measure it?

5. Forces in buildings

   • Static and opposed by equal and opposite forces (reactions)
     • Newtons 3rd law of motion
       • Downward force
         • Upward reaction
           • Construction example
             • Drawn in pencil and annotated in ink
             • Explained in your own words
