The climber will fall about the same height h in both cases, but they will be subjected to a greater force at position 1, due to the greater fall factor.. In lead climbing using a dynamic rope, the fall factor (f) is the ratio of the height (h) a climber falls before the climber's rope begins to stretch and the rope length (L) available to absorb the energy of the fall,
The Official Table of Drops, formerly issued by the British Home Office, is a manual which is used to calculate the appropriate length of rope for long drop hangings. Following a series of failed hangings, including those of John Babbacombe Lee , a committee chaired by Henry Bruce, 1st Baron Aberdare was formed in 1886 to discover and report on ...
Instead, the strength of a rope is tested by the number of standard test falls a rope can sustain before breaking. The test falls use an 80 kg weight for single ropes (55 kg for half ropes), and a fall factor of 1.7 (4 meter fall on 2.3 meters of rope). This tests simulates a very hard fall that would rarely occur.

A peak that appears to be the pinnacle of the mountain but upon reaching, it turns out the summit is higher (and further ahead). figure-four A figure-four move
With only a short length of rope to absorb the energy of a fall which can be much longer, the fall factor (which in rock climbing does not normally exceed two) can be high. [12] These high factors generate considerable forces which the human body, as well as most items of climbing equipment, cannot withstand, leading to serious injury and ...
For vigorous cardio, your heart rate should fall between 80 to 90 percent of your MHR, according to the AHA. Using the earlier example of a 35-year-old, this translates to a target heart rate of ...
