σ=230MPa (tensile strength)
ρ=1.85 g/cm^3 (density)
Strength/Weight = σ/ρ
Modulus/Weight = E/ρ
The Attempt at a Solution
Strength/Weight = σ/ρ = 230x106 N/m2 / 1850 kg/m2
= 124324.32 (Units?) ___Shouldn't this be unit less?
Modulus/Weight = E/ρ = 1.5x10 10 N/m2 / 1850 kg/m2
= 8108108.108 (Units?) ___Shouldn't this be unit less?
____Any help is appreciated, thank you__
