3-9. The σ-e diagram for a collagen fiber bundle from which a human tendon is composed is shown. If a segment of the Achilles tendon at A has a length of 6.5 in. and an approximate cross-sectional area of 0.229 in², determine its elongation if the foot supports a load of 125 lb, which causes a tension in the tendon of 343.75 lb.

As blood passes through the capillary bed in an organ, the capillaries join to form venules (small veins). If the blood speed increases by a factor of 4.00 and the total cross-sectional area of the venules is 10.0 cm2, what is the total cross-sectional area of the capillaries feeding these venules? (b) How many capillaries are involved if their average diameter is 10.0 μm?

As of August 27, 2020, the Philippines, through the Department of Finance has already borrowed $ 8.83 billion to fight against the health and socioeconomic crises inflicted by the COVD19 pandemic. (a) If payments were made at the rate of $1000 per second, how many many years would it take to pay off the debt, assuming no interest was charged? A one-dollar bill is about 15.5 cm long. If $8.83 billion one-dollar were laid end to end around the Earth's equator, how many times would they encircle the planet? Take the radium of the Earth at the equator to be 6378 km.
A uniform density sheet of metal is cut into the shape of an isosceles triangle, which is oriented with the base at the bottom and a corner at the top. It has a base B = 49 cm, height H = 15 cm, and area mass density σ. a) Consider a horizontal slice of the triangle that is a distance y from the top of the triangle and has a thickness dy. Write an equation for the area of this slice in terms of the distance y, and the base B and height H of the triangle. b) Set up an integral to calculate the vertical center of mass of the triangle, assuming it will have the form C ∫ f(y) where C has all the constants in it and f(y) is a function of y. What is f(y)? c)Integrate to find an equation for the location of the center of mass in the vertical direction. Use the coordinate system specified in the previous parts, with the origin at the top and positive downward. d)Find the numeric value for the distance between the top of the triangle and the center of mass in cm.
