1. Topic 6 and 7 Designing with Forces and Stable structures

2. Designers rely on these three methods to help structures withstand forces
Distribute the load throughout the the structure so that no single part is carrying all the load
Direct the forces along angled components so forces hold pieces together instead of pulling them apart.
Shape the parts to withstand the specific type of force they are likely to experience
