## Homework Statement

σ=230MPa (tensile strength)

E=15GPa (modulus)

ρ=1.85 g/cm^3 (density)

## Homework Equations

Strength/Weight = σ/ρ

Modulus/Weight = E/ρ

## The Attempt at a Solution

Strength/Weight = σ/ρ = 230x10

^{6}N/m

^{2}/ 1850 kg/m

^{2}

= 124324.32 (Units?) ___Shouldn't this be unit less?

Modulus/Weight = E/ρ = 1.5x10

^{10}N/m

^{2}/ 1850 kg/m

^{2}

= 8108108.108 (Units?) ___Shouldn't this be unit less?

____Any help is appreciated, thank you__
