The weight of your 1420 kg car is supported equally by its four tires, each inflated to a gauge pressure of 32.0 lb/in2 . What is the area of contact each tire makes with the road? If the gauge pressure is increased, does the area of contact increase, decrease, or stay the same? What gauge pressure is required to give an area of contact of 124 cm2 for each tire?

Blood pressure is normally expressed as the ratio of the systolic pressure (when the heart just ejects blood) to the diastolic pressure (when the heart is relaxed). The measurement is made at the level of the heart (usually at the middle of the upper arm), and the pressures are given in millimeters of mercury, although the units are not usually written. Normal blood pressure is typically 120/80. 1. How would you write normal systolic blood pressure if the units of...
A friend asks you how much pressure is in your car tires. You know that the tire manufacturer recommends 35 psi , but it's been a while since you've checked. You can't find a tire gauge in the car, but you do find the owner's manual and a ruler. Fortunately, you've just finished taking physics, so you tell your friend, "I don't know, but I can figure it out." From the owner's manual you find that the car's mass is...

A friend asks you how much pressure is in your car tires. Unfortunately, you have misplaced your gauge but confident in your knowledge of physics you tell your friend “I can figure it out”. From the owner’s manual you find that the car’s mass is 1500 kg and that the tire manufacturer recommends 31 psi. Assuming that each tire supports one-fourth of the weight of the car, you use a ruler to find that the tires are 15 cm wide...
Const Part A The tires of a car make 78 revolutions as the car reduces its speed uniformly from 90.0 km/h to 60.0 km/h. The tires have a diameter of 0.88 m.
