As I see it, 2 people carrying a 60 kg log seems saying very little about 3 people carrying a (longer) 85 kg one.
You would need far better synchronization of movements and people of the same height or exactly regulated straps for the tumpline and besides, a log 2.50 mt long behaves differently than a 3.50 mt long one when it comes to maneuverability.
- brudgers 4y agoA work song would simplify synchronization. And experience, as we see with contemporary sports, soldiering, musical performance, and dance.
- jaclaz 4y agoOf course experience and synchronization would matter. But if the hypothesis is that three people carried a 85 kg, 3.50 m long log, the experiment with two people carrying a 60 kg, 2.50 m is not representative of that. It is not like they couldn't find a third volunteer and attempt replicating exactly the hypothesis.
- brudgers 4y agoOne person forms a single pivot point. Two persons spaced a reasonable distance apart will damp rotation and hence torque. Adding a third person would limit log oscillations even more.
- jaclaz 4y agoWell, according to common engineering formulas, three supports inline will never get a third of the load each. It is a continuous beam with a distributed load (only own weight). Look for "Continuous Beam – Two Equal Spans – Uniformly Distributed Load" here: https://www.linsgroup.com/MECHANICAL_DESIGN/Beam/beam_formula.htm https://www.linsgroup.com/MECHANICAL_DESIGN/Beam/beam_formul... Hint: you'd better put the strongest guy in the middle.
