Impact forces during Lead Climbing
Impact forces during Lead Climbing Falls - a bonus episode of Belaying Masterclass
Understand what role rope length, stretch and friction plays in climbing falls and you will be an awesome belayer ;)
Ryan testing real climbing fall forces:
• Lead falls in climbing gyms - how muc...
There is no Gravity:
• Which Way Is Down?
And I intentionally skipped talking about fall factors... they almost mean nothing in lead climbing scenarios.
Fall factor = fall distance / rope length... But it misses the factor of how the climber was stopped (hard catch vs soft)
And you can't compare fall factors of lab experiments dropping weights vs real life, because climbers body will absorb 70% of the impact compared to rigid weight drop

And please don't tell anyone that 1kN is EQUAL to 100kg because not only it's approximation it also depends on the context ;)

Because that makes a big difference and is the main reason I do this project!
Deep Thanks!
