Aeronautical Engineering is a study of airplane design and technology. For a college degree in Engineering, the various colleges may use a different term for their degree program in this field. The courses required for the degree may also vary from one college to another and they may emphasize different types of specialities that branch off into exploring space to study of plasma fluid flow. Another term for a study in this field is Aerospace Engineering.Since Aeronautical Engineering can cover a wide variety of studies. Since aircraft have a unique method of construction out of light-weight material, aircraft structures is one branch of study. This can also have another specialty called dynamic structures or aerodynamics of structures. Other areas of study are propulsion, fluid dynamics, hypersonic flight.it means about astronaut engineering.

Desirable in scrummaging when the two packs form together. Without friction they would slip off which is dangerous. Friction is also desirable when making the tackle. And when sidestepping you need good grip. Undesireable when trying to evade the tackle.
Friction is desirable on your tyres and brakes. Tyres need to grip the road, to push the car forward, stop and go round corners. Brakes need friction to stop the wheels turning.
Very simply, desirable friction can be found on cars. Brakes are a good example. Another one is when you rub your hands together to produce heat. Striking a match is another and also uses a chemical reaction to produce a flame. All friction produces heat and many hundreds of uses have been found to utilise this heat.
When you are walking, when you are trying to stop your car, and lighting a match.

selective breeding, cloning, and genetic engineering are three methods for developing organisms with desirable traits >,< i have a cold :]
Yes it is desirable to some extent. For sure aeroplanes can't fly without moving on the ground (Frictional Force). Even a ship cannot move without friction. For erasing a mistake, the rubber has to show friction with the paper. But due to friction, there is a huge amount of energy is wasted. One way to discriminate it is: People can get injured themselves if they rub their hands hard on floors or sharp items.
selective breeding
Selective Breeding
The friction on a hinge needs to be small at the pivot point where the hinge rotates. This allows smooth movement and prevents the hinge from sticking or getting stuck. However, in other parts of the hinge, such as the pins or brackets, a small amount of friction may be desirable to provide stability and prevent excessive movement.
