The job of the heart and blood vessels is what is the answer?

Explanation:

Value of the cross-sectional area is as follows.

        A =

           = 3.45

The given data is as follows.

          Allowable stress = 14,500 psi

          Shear stress = 7100 psi

Now, we will calculate maximum load from allowable stress as follows.

                       =

                       = 50025 lb

Now, maximum load from shear stress is as follows.

                      =

                      = 48990 lb

Hence, will be calculated as follows.

                  = 48990 lb

Thus, we can conclude that the maximum permissible load is 48990 lb.
