Homework Statement
Onto a thick brass rod we attach equally long glass thread. At what temperature change will the glass thread break if the temperature coefficient of linear expansion for brass is
α1= 20 x 10 ^-6 K^-1, and for glass is α2= 7 x 10^-6 K^-1? Young’s (elastic) modulus for glass is E1= 7 x 10^10 N/m², and shear modulus for glass is σ1= 7 x 10^7 N/m².
Homework Equations
Linear thermal expansion: α(L)= ΔL/ L(0)ΔT
Young’s (elastic) modulus: E= FL(0)/ AΔL
The Attempt at a Solution
And from here I have no clue how to build a relationship between linear thermal expansion and elastic modulus and how to incorporate all the terms given to find the result.
Can someone please give me some hint?
Thank you for helping!
