1.
The climbing ropes provide how many percent of the tensile strength?
Correct Answer
A. About 80%
Explanation
The correct answer is "About 80%". This means that the climbing ropes provide approximately 80% of the tensile strength. Tensile strength refers to the maximum amount of tensile stress that a material can withstand before breaking or failing. In the context of climbing ropes, this indicates that the ropes can bear 80% of the maximum stress they are designed to handle without breaking.
2.
Ropes used for climbing can be divided into how many classes?
Correct Answer
C. 2
Explanation
Ropes used for climbing can be divided into two classes. This means that there are two main categories or types of ropes that are specifically designed and used for climbing purposes.
3.
The main purpose of which of the following is to allow the rope to be locked off with minimal effort to arrest a climber's fall?
Correct Answer
D. Belay devicesÂ
Explanation
Belay devices are designed to allow the rope to be locked off easily and quickly in order to arrest a climber's fall. They provide friction on the rope, allowing the belayer to control the rope's movement and stop the climber's descent in case of a fall. This is essential for the safety of the climber and the belayer, as it minimizes the effort required to stop a fall and prevents excessive slack in the rope. Harnesses, quickdraws, and carabiners are important components of climbing equipment, but they do not directly serve the purpose of locking off the rope to arrest a fall.
4.
Which of the following is an item of climbing equipment consisting of a tied or sewn loop of webbing that can be wrapped around sections of rock, hitched to other pieces of equipment or even tied directly to a tensioned line?
Correct Answer
C. Sling
Explanation
A sling is an item of climbing equipment consisting of a tied or sewn loop of webbing that can be wrapped around sections of rock, hitched to other pieces of equipment or even tied directly to a tensioned line. It is used to create anchors, extend protection, or for other purposes in climbing. Ascenders are devices used for ascending ropes, rappel devices are used for descending ropes, and harnesses are used to secure a climber to a rope. Therefore, the correct answer is sling.
5.
Which of the following is another name for Jumars?
Correct Answer
A. AscendersÂ
Explanation
Ascenders are another name for Jumars. Ascenders are mechanical devices used in rock climbing and mountaineering to ascend a rope. They have a camming mechanism that grips the rope when weight is applied, allowing the climber to move upward. Jumars is a brand name for ascenders, and it is commonly used to refer to this type of device. Rappel devices, belay devices, and quickdraws are different tools used in climbing for other purposes, and they are not interchangeable with ascenders or Jumars.
6.
Aid climbing is mainly different from Speed climbing because of which of the following?
Correct Answer
C. Aid climbing provides help for climbersÂ
Explanation
Aid climbing is mainly different from Speed climbing because aid climbing involves the use of artificial devices or tools to assist the climber in ascending the route. These devices can include ladders, hooks, and ropes, which provide support and help for the climbers to progress. On the other hand, speed climbing focuses on completing the route as quickly as possible, without the use of any artificial aids. Therefore, aid climbing provides help for climbers, whereas speed climbing is primarily focused on speed and does not involve any assistance.
7.
What's the main aim of Clean climbing?
Correct Answer
C. Not damaging the rock
Explanation
Clean climbing refers to a climbing technique that aims to minimize the impact on the natural environment, specifically the rock formations. The main aim of clean climbing is to avoid damaging the rock by using removable gear and leaving no trace behind. This approach promotes the preservation of the natural environment and allows future climbers to enjoy the same untouched beauty of the rock.
8.
Which of the following doesn't leave a scar?
Correct Answer
C. Slings
Explanation
Slings do not leave a scar because they are soft and flexible straps used in rock climbing to support the climber's weight. Unlike pitons, bolts, and copperheads, which are all metal objects used for anchoring and protection in climbing, slings do not penetrate the rock surface or cause any damage that would result in a scar.
9.
The first artificial climbing structure was constructed in what year?
Correct Answer
B. 1939
Explanation
The correct answer is 1939. This means that the first artificial climbing structure was constructed in the year 1939.
10.
Modern artificial climbing began where?
Correct Answer
C. United Kingdom
Explanation
Modern artificial climbing began in the United Kingdom. The United Kingdom has a long history of rock climbing and has been at the forefront of developing and popularizing artificial climbing techniques. The country is home to famous climbing areas such as the Peak District and the Lake District, where climbers have been pushing the boundaries of the sport for decades. The United Kingdom has also been instrumental in the development of climbing equipment and techniques, making it a significant hub for the sport.
