When it comes down golf balls, you might never know how much science goes into them. For reducing the air speed, and tweaking the turbulence experienced by a ball, there must be emphasis put on aerodynamics. A ball's surface structure is crucial for its flight performance.
It was invented by a Scottish man named James Hargreaves. He was the first person to use a rubber bladder filled with air to create a softball. This feather ball, called the Featherie, was handmade by a local artist. Handcrafted feather dolls were made by spending countless hours compacting goose feathers inside an animal skin bag. When the leather was wet, the feathers were stuffed into the ball by hand. After the leather dried, the feathers were compressed further and made the ball harder.
Because of the extreme amount of time and effort that went into creating these golf balls, they were often more expensive to produce than the gold clubs themselves For this reason, some could not afford to play the golf game, and it forced them to change the golf ball.
Next up was the Guttie golf ball, which was made from the rubber from a Gutta tree. The abundance of the material and ease of forming the substance made these balls cheaper and golf more popular than ever before. One drawback of the Guttie ball was that it was harder than the Featherie meaning it traveled shorter distances and slower. For this reason, scientists are now focusing on reducing the air resistance. This analysis was the basis for the addition of dimpled golf balls today.
These new dimples were designed to reduce the air drag experienced by golf balls during flight. A new study shows that a smooth ball leaves pockets of low pressure around it when in flight. These pockets create drag and reduce the balls' distance and stability. Dimples help decrease the drag around the ball by decreasing the pressure around the ball.
Dimples disturb the flow of air around the ball, causing turbulence. This causes the air to envelop the ball more closely than if it were a flat ball. This closer grip the ball has on the air causes a finer stream, which results in less drag. This results in a smaller wake and less drag. Dimples allow golfers to put spin on their shots, which allows them to control the trajectory of the ball.
When buying a ball, consider the amount of precision, science, and technology that goes into creating a high quality one.## Inputs There are now a huge range of different types of golf ball for different conditions or golfing strategies. Some golf balls give you better control than others, while others offer more power or distance. More expensive golf balls tend to be of higher quality than cheaper ones, because they require more precise manufacturing processes. All golf balls depend heavily on physics and machinings.
Golf balls can be divided into two main categories: solid and wound. Solid balls include three-piece, four-piece, and multi-layer balls. Wound balls consist of a liquid center surrounded by tensioned elastomeric thread. In general, solid golf balls have lower spin rates than wound balls but typically travel farther due to their higher initial velocity.
Solid golf balls generally have either been completely formed (i.e., molded) by methods such as injection molding or compression molding or have had certain portions added after being formed. After formation, the golf ball is then finished with additional coating(s), topcoats, intermediate layers, cover stock, etc.
Wound balls are usually constructed from an elastic thread wound under tension around a solid or semi-solid core. They may also contain foam or other non-woven materials in the cover.
A typical wound ball includes a fluid-filled bladder covered with a natural or synthetic outer skin. Such a wound ball can be produced by winding yarn around a solid or semi solid core at a ratio of about 20:1 to about 200:1 (the “cover”). As such, the resulting ball will have a soft feel and high spin rate. However, wound balls typically do not provide great distance because of their relatively small size. Additionally, wound balls are difficult to manufacture and often lack durability.
A variety of techniques exist for finishing the surface of a golf ball. For example, U.S. Pat. No. 5,976,443 discloses a method of forming a polyurethane cover comprising applying a first polyurethane material to the surface of a golfball and thereafter applying a second polyureth
