Problem 12P

IP The weight of your 1420-kg car is supported equally by its four tires, each inflated to a gauge pressure of 35.0 lb/in2. (a) What is the area of contact each tire makes with the road? (b) If the gauge pressure is increased, does the area of contact increase, decrease, or stay the same? (c) What gauge pressure is required to give an area of contact of 116 cm2 for each tire?

Step-by-Step Solution:

Solution 12 P

a.)

Step 1 of 4

We have to find the area of contact each tire makes with the road.

The pressure in each tire of the car is 35.0 lb/in2 and four tires of the car is in contact with the road.

Thus, the area of the contact is given by

Where,

Area of four tires

= 4 in m2

due to the weight of the car

in N

pressure in the tire of the

car = 35.0 lb/in2
