Calculation of Mass and volume of parts



The density of the materials chosen is:
Material Density
Carbon steel 7850 Kg/m3
Aluminium 2600 Kg/m3


By multiplying the density by the volume the mass is obtained:

Component Volume Mass Material
Centre console 0.03770m³ 98.018Kg Aluminium
Large leg connector 0.00947m³ 24.621Kg Aluminium
Small leg connector 0.00397m³ 10.327Kg Aluminium
Feet 0.00225m³ 5.85Kg Aluminium
Small leg 0.00106m³ 2.757Kg Aluminium
Large leg 0.00148m³ 3.848Kg Aluminium
I-Beam connection 0.000268m³ 2.104Kg Carbon steel
1.1m Beam 0.00715m³ 56Kg Carbon steel
1.2m Beam 0.0078m³ 61Kg Carbon steel


The total mass of our crane with every component connected and with 3xFeet, 3xSmall leg and 3xLarge leg is:

289.435Kg

    So what is the importance of mass in this context ?
    In any work explain to the reader why you are doing something and what the results mean.
    ie.
    - Is your prime interest the manual carrying of components ? Whether the crane as a whole will be too heavy for the landrover ? To consider the weight of the crane as an additional load on the crane ? To estimate material costs (not very accurate) ?
