top 25 mechanical engineering interview questions & answers
1. Large tyres provide larger surface area touching the ground, thus providing the more pulling power. Basically tractors have larger rear tyres because tractors don’t have to operate at higher speeds, thus getting the same ground speed with larger tyres. Moreover gear ratios don’t have to be as high as b/c of the tyres.
Tyres colour is black due to the proportion of carbon mixed in it during the vulcanization of the rubber, to make the tyre shear resistant. Without vulcanization tyres won't be able to bear the friction heat and stress of the road. Thus carbon is responsible for giving tyres the prominent black colour. Adding of carbon prevents tyres from rapidly deteriorating because when ozone combines with the ultraviolet light from the sun. It attacks the polymer of the tyre.

Are You Ready For Introduction Of Engineering Mechanics (part-1)
Hello guys, today we are going to discuss about the Basic
introduction of the engineering mechanics So guys, Let’s start
ENGINEERING MECHANICS:
The subject of
Engineering Mechanics is that branch of Applied Science, which deals with the
laws and principles of Mechanics, along with their applications to engineering
problems. As a matter of fact, knowledge of Engineering Mechanics is very
essential for an engineer in planning, designing and construction of his
various types of structures and machines
