# Rectangular plate: ideal solid, uniform material
length = 500 mm in 100..1000
width = 200 mm in 50..500
thickness = 20 mm in 5..50
density = 2700 kg/m^3 "Illustrative aluminium density"
part plate "Plate": box length, width, thickness
volume := length * width * thickness [m^3]
mass := density * volume [kg]
check mass budget: mass <= 10 kg
scenario wider: width = 300 mm
