A portable loading ramp can be made from aluminium alloy or low-carbon steel. Ramps made from either material have the same shape and a volume of 0.0060 m³.
The ramp must:
| Material | Density in kg/m³ | Maximum supported load in kg |
|---|---|---|
| Aluminium alloy | 2700 | 650 |
| Low-carbon steel | 7800 | 900 |
Which material should be used for the ramp? Show calculations and use both requirements to justify your answer.
