Question

如题所述

Answer 1

I. Damper Assembly Description
1. The damper assembly includes a spherical elastomer bearing member, which is operable for accommodating relative motion and vibration.
2. Additionally, the damper assembly features a flat elastomer bearing member, which also operates for accommodating relative motion and vibration.
3. The assembly includes a substantially rigid transition shim disposed between the spherical elastomer bearing member and the flat elastomer bearing member. This shim couples the spherical elastomer bearing member to the flat elastomer bearing member.
4. Furthermore, the damper assembly comprises a tension member attached to the substantially rigid transition shim. This tension member is operable for prepressing the spherical elastomer bearing member and increasing the cocking stiffness of the damper assembly.
II. About Extreme Sports
1. Extreme sports, also known as action sports or adventure sports, are popular activities perceived as having a high level of inherent danger and are counter-cultural.
2. These activities often involve speed, height, a high level of physical exertion, and highly specialized gear or spectacular stunts.
3. The definition of an extreme sport is not exact. For instance, although studies show that road cycling ranks as the sport with the highest rate of injury, it is not considered an extreme sport because it is not counter-cultural.
4. The term's origin is also unclear, but it gained popularity in the 1990s when it was picked up by marketing companies to promote the X Games.
5. In recent decades, the term extreme sport was further promoted by X Games, a multi-sport event created and developed by ESPN. The first X Games were held in Newport, Providence, Mount Snow, and Vermont in the United States.
III. Why People Love Extreme Sports
1. Parkour is a sport activity with the purpose of moving from one place to another as efficiently and quickly as possible, using only the physical skills of the human body.
2. It is used to overcome obstacles, which can be any obstacle in the environment, such as fences, stone pillars, walls, and bars, and can be practiced both in urban areas and rural areas.
3. Founded by David Belle in France, parkour focuses on efficient movements to develop the training of the body and mind, to be prepared to overcome obstacles in an emergency.
