(a)
Find the road speed (in miles per hour) at which the tire is being balanced.
(a)
Answer to Problem 108E
Explanation of Solution
Given:
Diameter of the tire is 25 inch and number of revolution per min is 480.
Concept Used:
1 revolution = circumference of the tire.
Circumference =
Calculation:
Given: Diameter of the tire is 25 inch&number of revolution per min is 480.
Circumference =
Now multiply with revaluation per minute = Circumference
=
Now convert inch/min to mile / min =
Now convert mile/min to mile/hr
Thus the road speed is
Thus,
(b)
Find the rate of the spin balance set so that the tire for 70 miles / hr
(b)
Answer to Problem 108E
Explanation of Solution
Given:
The diameter of the tire is 25 inch and the tested rate is 70 miles / hr
Concept Used:
1 revolution = circumference of the tire.
Circumference =
Calculation:
Given: Diameter of the tire is 25 inch& tested speed is 70 miles/ hr
Circumference =
Convert the rate from miles / hr to miles/minute =
Convert the rate from miles / min to inches/min
Revolution per minute =
Thus, the rate of spin balance is
