The car's differential gear will transfer power equally to both drive wheels, and if one has no friction at all (sand, water, or not touching ground) it will spin freely. In loose mud or water, both wheels will spin.
To help protect the vehicle and other vehicles behind you from flying mud and small stones.
It means that when you get the rear wheels stuck in mud or snow or something, when you have the vehicle in gear and try to move, the rear wheels get equal power so even if one wheel is free, it won't spin. Other names for the same thing is posi trac, or limited slip differential.
When a car gets stuck in the mud, two things are at work. First of all the mud is very slick. The tires of the car have no traction and simply spin helplessly trying to move the heavy weight of the car. Secondly, mud, if it is deep, has suction. It literally sucks the car's tires, holding the car in the mud. Combine this with mud's slickness and your car is literally stuck.
Mud flaps are required on commercial vehicles in all states.
A mud flap is a part of a car. It is used to protect cars and pedestrians from mud which is thrown from circulating wheels, which by the force of centripetal, throw mud around them.
In cars, it is a barrier that surrounds the wheels. To block water and mud.
Mud flaps are usually used to help with rocks and mud from building up underneath near the wheels.
All all-terrain vehicles are equally equipped to drive in muddy areas. Kawasaki and Sportman all-terrain vehicles are the highest rated all-terrain vehicles to be used in mud.
Also known as wings or mud guards, they are the metal part over the wheels to keep water and mud from splashing.
Any mass in motion remains in constant uniform motion (constant speed and direction) unless acted upon by an external force. At any instant in time, the mud particle is moving tangentially on the wheel. If the adhesion between the wheel and the mud is strong enough to transmit a force to the mud and cause it to alter its direction of motion, then its direction of motion will change to follow the wheel. If the mud isn't stuck to the wheel tight enough to transmit the required force, then its direction of motion will not change enough to follow the wheel and it will separate. At the instant of separation, the force goes away, and the mud continues in straight-line motion.
The belts are called tracks. Normal vehicles, with just wheels, tend to sink easily into the mud when off a paved road, and become stuck. All the weight of the vehicle is pressed into the ground at four relatively small areas, making those areas likely to be pushed deeply into mud by the weight of the vehicle. Even before WWI inventors had realized that spreading the vehicles weight with the use of tracks instead of wheels would keep the vehicle from becoming mired in the mud. These were called caterpillar tracks. In WWI this innovation was adopted for a new use, when battle tanks were invented. The wider the track, the better the vehicle is able to keep from sinking into the mud, but this was not really understood until WWII. The tracks use the same principle as snowshoes, developed by Eskimos, that look a little bit like tennis rackets. The snowshoes spread the weight of the foot over the top of the snow, keeping the foot from sinking into the snow. Most of the wheels on the side of a battle tank are there just to give support and shape to the tracks. These are called bogey wheels. Only the back wheels on either side are connected to the engine and supply power to the tracks. These back, drive wheels are cog wheels, geared, with teeth. These teeth fit into slots on the inside of the track to drive the tracks around.
