Hmmm. Let me add in something.

Response to video:
1st comment: Anchor system is essential for rock climbing.

Reply: Definitely. Duhz.

2nd comment: Yes. A good two point anchor system is one that has a large angle in between the two anchors.

Reply: For the two anchor points to be placed as far apart from each other as possible, it would be a little difficult.

3rd comment: Well, I think a good two point anchor system is one which the two anchors are perpendicular to each other but the vertical positions of the two anchors are not on the same horizontal level.

Reply: Possibly.

4th comment: Is it right to say anchor systems are safest when they equalize forces?

Reply: Yes, possibly.

I feel that anchor systems are safest when they equalize forces.
- For the two anchor points to be able to support as much downwards force as possible, the two anchor points should be as close to each other as possible
- Thus the force can be distributed proportionally between two anchor points

Well, I suppose that it is commonly agreed on an international basis that two is the required number for this type of anchoring. Increasing the number of straps is an interesting solution however, we need to take into consideration the structure of the harness as well as how it is connected to the anchor points and whether three is a feasible idea.

A two point anchor system is useful, however, too large an angle will cause high tension in the ropes, thus it might not be that safe. the two point anchor system ensures that the resultant force to be 0, just that it might not be good when the angle is too big

Group Discussion ( Elliott, Marcus, Kenneth)
The vector sum of the 2 ropes from the two anchor points will be equal to the max weight that the anchor system can support.
Therefore, the smaller the angle, the safer the climb as more weight can be supported by the anchor system

Discussion (Andrew Tan, Joshua, Zhen Tao)
That is right? Right? I mean if the angle affects the amount of tension, by adding one more strap, it would reduce the amount of tension in each string. However, why does no one do that
