MATERIALS

Our crane must be strong and durable. In order for us to succeed in choosing the best material, we have to look into many different properties of different materials.

We have chosen to decide out of steel and aluminium for the material of our crane. Below you can see some advantages of each material

Aluminium:

Aluminium has the following properties:

Density, 2.7 Kg/m^3.
Yield strength, 55 MPa
Tensile strength, 125 MPa
Young's modulus, 69 GPa

This would be an ideal material to use for the crane. It is low in weight, does not corrode easily and can be melted easily

Steel:

Steel has the following properties:

Yield strength, 250 MPa
Density, 7.85 Kg/m^3
Young's modulus, beteen 190 and 210 GPa
Tensile strength, 280 MPa

Steel would also be an ideal property, however it is very costly compared to aluminium.
