An automobile weighing 1.19 x 104 N has weight equally distributed over its wheels. The weight of the car causes each tire to be slightly flattened on the bottom so that there is a surface area in contact with the road. The gauge pressure of the air in the tire is 1.90 x 105 Pa (27.55 lb/in2). Find the area of contact, assuming that the only forces on the section of tire in contact with the road are the air pressure and the normal force exerted by the surface of the road.
A rectangular solid made of aluminum has a density p= 2.70 g/cm³. The dimensions of the solid are shown below. The solid is placed on top of a truncated cone whose circular ends have the dimensions shown. The bottom of the rectangular solid down on the top surface of the cone. Find the pressure (in N/m²)between those two surfaces. (Ignore air pressure.) (1 kg = 1000 g, 1 m 100 cm) presses 10.0 cm 8.00 cm 15.0 cm r= 2.00 cm R = 6.00 cm

A 72.0-kg man lies on his back on a bed of nails, with 1,202 of the nails in contact with his body. The end of each nail has area 1.14 ✕ 10−6 m2. What average pressure is exerted by each nail on the man's body?
At a given instant, the blood pressure in the heart is 1.4 x 10^4 Pa. If an artery in the brain is 0.49m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow.
Suppose you measure a standing person’s blood pressure by placing the cuff on his leg 0.525 m below the heart. For this problem, assume that there is no loss of pressure due to resistance in the circulatory system (a reasonable assumption, since major arteries are large). The density of blood is 1.05×103 kg/m3 a. Calculate the systolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the top (and greater) number is the systolic pressure. b. Calculate the diastolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the bottom (smaller) number is the diastolic pressure.
A 79-kg swami lies on a bed of nails with his body supported by 2,000 nails. The area of the point of each nail is 1 mm^2. If the threshold pressure for pain is 1 mpa, how unpleasant is the experience for the swami? What if the point area is 0.1mm^2?
Artificial diamonds can be made using high-pressure, high-temperature presses. Suppose an artificial diamond of volume 1.28 ✕ 10−6 m3 is formed under a pressure of 4.60 GPa. Find the change in its volume (in m3) when it is released from the press and brought to atmospheric pressure. Take the diamond's bulk modulus to be B = 194 GPa. (Assume the system is at sea level.)

Problem 1: A certain rigid aluminum container contains a liquid at a gauge pressure of P0 = 2.02 × 105 Pa at sea level where the atmospheric pressure is Pa = 1.01 × 105 Pa. The volume of the container is V0 = 2.15 × 10-4 m3. The maximum difference between the pressure inside and outside that this particular container can withstand before bursting or imploding is ΔPmax = 2.41 × 105 Pa.For this problem, assume that the density of air maintains a constant value of ρa = 1.20 kg / m3 and that the density of seawater maintains a constant value of ρs = 1025 kg / m3. What is the maximum depth dmax in meters below the surface of the ocean that the container can be taken before imploding?
Artificial diamonds can be made using high-pressure, high-temperature presses. Suppose an artificial diamond of volume 1.12 ✕ 10−6 m3 is formed under a pressure of 5.50 GPa. Find the change in its volume (in m3) when it is released from the press and brought to atmospheric pressure. Take the diamond's bulk modulus to be B = 194 GPa. (Assume the system is at sea level.)
