(II) At depths of 2000 m in the sea, the pressure is about 200 times atmospheric pressure (1 atm = 1.0 x 10⁵ N/m²). By what percentage does the interior space of an iron bathysphere’s volume change at this depth?

What is the maximum tension possible in a 1.00-mm-diameter nylon tennis racket string?

What is the maximum tension possible in a 1.00-mm-diameter nylon tennis racket string? If you want tighter strings, what do you do to prevent breakage: use thinner or thicker strings? Why? What causes strings to break when they are hit by the ball?

(I) What is the difference in blood pressure (mm-Hg) between the top of the head and bottom of the feet of a 1.75-m-tall person standing vertically?

(III) Water stands at a height h behind a vertical dam of uniform width b. Use integration to show that the total force of the water on the dam is F = 1/2 ρgh²b.

Assume the supports of the uniform cantilever shown in Fig. 12–79 (m = 2900 kg) are made of wood. Calculate the minimum cross-sectional area required of each, assuming a safety factor of 9.0.

How high would the level be in an alcohol barometer at normal atmospheric pressure?

(III) A beaker of liquid accelerates from rest, on a horizontal surface, with acceleration α to the right. How does the pressure vary with depth below the surface?
