The following three σ-ϵ data points are provided for a titanium allow for aerospace applications: ϵ = 0.002525 (at σ = 300 MPa), ϵ = 0.005051 (at σ = 600 MPa), and ϵ = 0.008029 (at σ = 900 MPa). Calculate E for this alloy.

i just learnt this recently but i need to look through my notes again

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
