Steel has an elastic modulus of 30 x 10^6 psi while that of copper is 18x10^6 psi. A bar of each of these is subjected to a stress of 3000 psi. A.) calculate the strain of each material. B.) Which one is stiffer and why?
Yeeeee- no. Good luck with that, buddy.
With enough adrenaline, anything is possible.
i cant, good luck with finding one that can
A) Stress / Elastic modulous Strain Think of the above equation being like the spring law in physics. F kx. F is the force (or stress) x is the displacement (or strain) k is the spring constant (or modulous) same concept different name. B) a material with a smaller strain can be considered as the stiffer material
