Question

A cylindrical, 0.500-m rod has a diameter of 0.02 m. The rod is stretched to a length of 0.501 m by a force of 3000 N. What is the Young's modulus of the material?

Answer 1

Y = 4.775 x 10⁹ Pa = 4.775 GPa

Step-by-step explanation:

First, we calculate the stress on the rod:

Now, we calculate the strain:

Now, we will calculate the Young's Modulus (Y):

Y = 4.775 x 10⁹ Pa = 4.775 GPa
