1. Use a “Limit” stage to find materials with modulus E
180 GPa and embodied energy H_m, 30 MJ/kg.

2. Use a “Limit” stage to find materials with yield strength σ_y. 100 MPa and a carbon footprint CO₂
 kg/kg.

3. Make a bar chart of embodied energy H_m. Limit the selection to polymers alone by creating a subset that only contains the “Polymer” folder. Which polymers have the lowest embodied energy?
