1. DTB3.2.1

   Structures in everyday products

   Structures are present in the design of everyday products.

2. DTB3.2.2

   Calculating Young’s Modulus

   Young’s Modulus is the measure of stiffness of a material.

3. DTB3.2.3

   Why structures fail

   Structures fail due to overloading, material choice, size and shape.

4. DTB3.2.4

   Force diagrams

   Forces acting on a structure or within a beam can be represented diagrammatically.

5. DTB3.2.5

   Applying safety factors

   Safety factors (SFs) are a way to design in contingency to prevent failure from overloading a structure.
