- Be able to use the stiffness to predict how rubber specimens of different shapes will deform
- Understand why rubber is known as an "entropy spring"
- Appreciate that the stiffness of rubber rises with increasing temperature, in contrast to all other materials
- Understand the pressure-size relationship exhibited by a balloon
