2. Changing Materials to Make Them Stronger
Corrugation
Lamination
Strengthening Component Arrangements
Changing Methods of Fastening

3. Corrugation
Forming a material into a wave-like folds or ridges. Examples: Cardboard and metal

4. Lamination = LAYERS! Gluing layers together to make it stronger
Kitchen countertops top layer is laminated on top of wood
Plywood
Glass in vehicles

5. Strengthening Component Arrangements
Making greater uses of trusses and arches by arrangement
Adding small supports for reinforcement
Tie – resists tension
Strut – resists compression

6. Changing Methods of Fastening
Fastening is a way to hold materials together
Changing screws  nails
Changing from mass  cement to hold pieces together
