A 40kg boy whose leg bones are 4cm² in area and 50cm long falls through a height of 50cm without breaking his leg bones. If the bones can stand a stress of 0.9 X 10^8 N/m². Calculate Young's Modulus for the material of the bone

# Young's Modulus
Y = Stress / Strain = (F/A) / l / L
Y = 0.9 × 10^8 / 0.5 = 9 × 10^8 /5
= 1.8 × 10^8 ...
