A metal rod that is 4.00 m long and 0.50 cm2 in cross-sectional area is found to stretch 0.20 cm under a tension of 5000 N. What is Young’s modulus for this metal?

Solution 27E Step 1 : Introduction In this question, we need to find the young’s modulus of the metal Data given Length of the rod l = 4.0 m Area of cross section A = 0.50 cm = 0.50 × 10 m 4 2 Stretch distance l = 0.20 cm Tension F =T5000 N
