On a cool morning, when the temperature is 13 C, you measure the pressure in your car tires to be 30 psi. After driving 50 mi on the freeway, the temperature of your tires is 42 C.What pressure will your tire gauge now show?
T1 = 13 C
T2 = 42 C
P1 = 30 psi
P2 = ?
By perfect gas equation, as V is constant,
P1V = RT1
P2V = RT2
P2/P1 = T2/T1
P2 = P1xT2/T1
P2 = 30×42/13 = 96.92 psi
Determine the number of revolutions through which a typical automobile tire turns in 1 yr. Suppose the automobile travels 11000 miles each year on tires with radius 0.220 m.
??? revolutions
I would appreciate any help. Please show me how to solve it in detail, I learn best that way!
Distance/revolution = Circumference of tire = 2πR = 6.28(0.220) = 1.38 m
Total Distance = 11,000 miles = 1609 m/mile x 11,000 = 17,699,000 m
Total Distance/Distance per revolution = 17,699,000/1.38 = 1.28e7 revolutions ANS
Hi, I hv done Automobile Engineering but got employed in a good software company as a trainee. But as its( Computer Programming) not my background, I am worried that because of this i am going to get some trouble in future. Can i expect a good scope in software programing ?I am very much sure that i can handle this programming thing very well. But still i would like to know your view regarding this.
Yes, Automobile Engineer can become a successful S/W Developer. But see that you Study your Basics well[Languages Like C, C++, Core Java]. It is also important for you to update yourself at regular intervals. There are many websites which conduct free online exams in all the languages, attend those to See how far you are ready to work in S/W industry. If required do Certifications in the language that you are familiar with.
