The longitudinal groves in a serpentine belt (for example), will give it more surface contact area so it can get better grip. They will also help keep it aligned.
The transverse groves will help improve flexibility of the belt without significantly affecting the durability.

It's for stability. The groove usually matches exactly with a cup from the same tea set. it's designed to keep the cup on the saucer.
To prevent objects being conveyed on the belt from sliding around on the surface of the belt.
Since the determination of the fact that Earth is spherical as opposed to flat, all scientists (after a short lag period) have accepted that it is so.

Take the deck off. On top of the deck is the belt diagram if that is the one you were wanting. Here's a tip: Check the pulleys and the back of the belt will ride on what is called a flat idler (flat part) and the inside of the belt will ride on a "V groove idler". If you take this into account it will be easier to install your belt.
Sleep and creep does not take place for the v-belt. compare to flat belt it will be very less.
A serpentine belt is one that drives multiple components with both sides of the belt. The ribs can be either poly groove or micro groove, depending on year, make, model, and engine.

A belt drive is an alternative to a chain drive (as you would normally find on a bicycle or motorcycle). There are several types of belt used in belt drive systems including V-belts and toothed belts. The more common is the V-belt. A cross section of the pulley used shows that the belt runs in a V-shaped groove. Washing machines, older cars, and machinery use this type of belt system. The toothed belt is normally wide and flat with teeth on the inside to prevent slippage. Harley Davidson motorcycles use these, as do super-charged engines in cars.
I've got the alt on the inner groove, the water pump on the middle groove, and the ps pump on the outer groove. I don't know if this is correct but it works for me.
A pulley for a drive belt.
Look on the back side of the serpentine belt (the side of the belt with the ribs). If any of the ribs are cracked the belt should be replaced. Take a look at the physical condition. If it is cracked on the inside (groove or V side) it needs to be replaced.
The friction coefficient of V-belts is generally higher than that of flat belts due to increased contact area and wedging action between the belt and pulley. V-belts provide better traction and reduce slip, making them suitable for high-torque applications compared to flat belts. Additionally, V-belts can accommodate higher power transmission due to their design and ability to handle side loads better.
"B" series v-belts are wider and transmit more horsepower than "A" series belts. V-belt sheaves for A and B series belts often will accept both A or B series belts. These sheaves will usually have pitch diameters stamped on them for both A and B. You will notice the diameter for the "A" belt will be a little smaller pitch diameter because the "A" belt will ride "down" in the groove farther than the "B" belt. You should be able to "google" on something like "gates v-belts" to see examples. DNC
