11.9 Exercise 10

Avg difficulty 2.5

During heavy lifting, a disk between spinal vertebrae is subjected to a 5000-N compressional force. (a) What pressure is created, assuming that the disk has a uniform circular cross section 2.00 cm in radius? (b) What deformation is produced if the disk is 0.800 cm thick and has a Young’s modulus of 1.5×109N/m21 . 5 \times \text{10}^{9} \text{N}/\text{m}^{2}?
