Automobile Engineering Interview Question and Answer


1. Explain the reason that why big tyres are used in rear of vehicles.
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.

2. What is kingpin offset? State some of its application.
The kingpin offset is the part, basically called as pivot used in the steering of the vehicles. This offset helps in rotating of the steering and thus it’s very useful in steering mechanism of the cars.
Applications: This is also used to measure scrub radius with the help of geometric parameters of wheel plane above and below ground level. 
It provides directional stability to the vehicles when it i combined with the caster.
