There is a disk of cartilage between each pair of vertebrae in your spine. Young's modulus for cartilage is 1.0 × 106N/m2. Suppose a relaxed disk is 4.0 cm in diameter and 5.0 mm thick.

If a disk in the lower spine supports half the weight of a 76 kg person, by how many mmmm does the disk compress?

Express your answer using two significant figures.

Expert Solution

first, i draw a figure showing the condition of question, here thickness is length as shown in figure. Now, force supported by disk is half the weight of person. After applying the formula, disk compress by 1.47 mm.
