In regions of the cardiovascular system where there is steady laminar blood flow, the shear stress on cells lining the walls of the blood vessels is about 20 dyne/cm2. If the shear strain is about 0.008, estimate the shear modulus for the affected cells. Note 1 dyne = 1 g ⋅ cm / s 2 and 1 N = 10 5 dyne

Answer:

[tex]250[/tex] N/m2

Explanation:

Shear stress on cells lining the walls of the blood vessels  is equal to [tex]20[/tex]20 dyne/cm2

In terms of Newton/square meter, shear stress is equal to

[tex]20*\frac{dyne}{cm^2}  (\frac{10^{-5}N}{1 dyne} )*(\frac{1 cm^2}{10^{-4}*m^2} )\\= 2.0[/tex] N/m2

Shear modulus is equal to shear stress divided by shear strain

Thus, shear modulus is equal to

[tex]= \frac{2.0}{0.008} \\= 250[/tex]N/m2
