benefit of using four wheeler over Normal Wheelrs

why four wheelers safe than two wheelers

why four wheeler safe than two wheelers

The phenomenon of traction helps in determining the amplitude of torque and turning of the wheel. The forces that are applied by the ground to the wheel or the wheel that applies to the ground is also traction. If there is low-traction then the torque applied is due to traction and not due to the engine. There is no way to harness or control the power if tires won’t stick to the ground.

Traction also depends on the weight of the car. As the weight of car increases traction also increases. As the car moves the weight also get shifted. For example, the weight of the car shifts to the outside wheel if the car turns and the weight of the car will shift to rear wheel if the speed of the car increases.

One more factor that affects traction is the coefficient factor. It determines the relationship between the surfaces and the surface of the road to the friction of the tyre. In our case, the coefficient factor is the friction between the road on which the car is driven and the weight on the tyre. Coefficient factor mostly depends on the surface it is being driven and the type of tyre used.

It can be explained with the help of an example. All have seen the car races and the track on which they run. The dry track which is provided to them serves as one of the reasons they are able to run their cars at such a high speed. If the same cars are made to run on the muddy tracks their coefficient fraction would be zero. Thus, a coefficient fraction is high on dry tracks and zero or low on muddy tracks.

There are basically two kinds of contact that tyres can make. One is the static contact and the other is the dynamic contact where static contact means that the contact between the road and the tyres are relative to each other whereas a dynamic contact is one where the tyres and the roads are not relative to each other. Moreover, in static contact, the coefficient fraction is higher than that of dynamic contact.

It is quite simple to understand that when we are driving four wheeler instead of two-wheeler than more force is applied and there are chances that vehicle may slip. There is a condition called an off-road condition in which there are chances for two-wheeler that they may apply low-traction in situations where a large amount of force is needed. For example, in muddy areas or in slippery hills. For all these conditions four wheeler is better than the two-wheeler.

At last, the inference that can be drawn from this article is that four-wheelers are better than two-wheelers because there are situations where four-wheeler uses a large amount of force to drive a car than two-wheeler whose friction usually decreases in muddy areas.
