Calculate the maximum force in newtons exerted by the blood on an aneurysm, or ballooning, in a major artery, given the maximum blood pressure for this person is 150 $\mathrm{mm} \mathrm{Hg}$ and the effective area of the aneurysm is 20.0 $\mathrm{cm}^{2}$ . Note that this force is great enough to cause further enlargement and subsequently greater force on the ever-thinner vessel wall.

so we know the pressure is equaling a force per unit area and so the force would simply be equal to the product between the pressure and the area. And so the force would be equaling. 150 millimetres of mercury multiplied by 133 Newtons per square meter per millimeter of mercury multiplied by 20 square meters, multiplied by 10 to the negative forth square square meters per square centimeter. So my apologies 20 square centimeters multiplied by 10 to the negative fourth square meters per square centimetre. And so we can then say that the force exerted would be equaling 39.9 Newton's. This would be the maximum force exerted by the blood. That is the end of the solution. Thank you for one.
