From Young's modulus formulae, we get,
Y = (F/A)/strain
10^20 = (855/(9.5 * 10^-4)(strain)
strain = 855/(9.5 x 10^16)
          = 90 x 10^-16

Your leg bones (cross-sectional area about 9.50 cm2) experience a force of approximately 855 N when you walk. Find the fractional amount your leg bones are compressed by walking. Taking young modulus of bone to be Y = 1010 N/m2
