Two plastic rulers (R1 and R2) were subjected to the same stress. Whereas R1 extended by only 10% of its original length, R2 extended by x% or its original length. A) What is the stress applied given the following Young’s moduli: E1 = 1000 MPa, E2 = 600 MPa B) Find x% of R2 C) Which of these rulers is made out of a more compliant material?
