1. Equation F/A=-Y[tex]\alpha[/tex][tex]\Delta[/tex]T (thermal stress) gives the stress required to keep the length of a rod constant as its temperature changes. Show that if the length is permitted to change by an amount [tex]\Delta[/tex]L when its temperature changes by [tex]\Delta[/tex]T, the stress is equal to F/A = Y(([tex]\Delta[/tex]L/L[tex]_{}0[/tex])-[tex]\alpha\Delta[/tex]T) where F is the tension on the rod, L(naut) is the original length of the rod, A its cross-sectional area, alpha its coefficient of linear expansion, and Y its Young's modulus.
i don't know where to start can somebody help? this thermal stress is stressing me out
