At the time of this post 202 people have read my above post yet there are no conversations, so here is a conversation starter:
Anyone like physics?
Let's have your thoughts on the physics of getting a vehicle unstuck.
Why?
Understanding the physics of our task enables us to optimize what is working for us which is important in difficult situations where getting a vehicle unstuck is marginal or won't happen.
Next proposed (participation) topic: What is the difference between tow straps and recovery straps and how are they most effectively used? You start.
I'm a scientist. Not the new sort of "consensus science," but the traditional definition of science.
What's particularly interesting to me on what works and how what works better is counterintuitive. Common sense has it that what works best is what the experienced are doing. But, are they doing that because they really know? No. They just figure it must be best because it looks best (as in the previous example of aggressive knobby tread on loose sand) or everyone does it that way.
On the topic of getting vehicles unstuck, my observation is there is often a lot of emotion, frustration with what doesn't work and even end-of-the-world sort of desperation which is not the best time to discuss physics even though it is often exactly what they need.
Example: I was reading an article of a death from a couple being stuck in sand long enough for exposure to be a factor. The rescuers recovered the vehicle simply by letting out most of the air pressure out of the tires and driving off without need for any other action. If the elderly couple had this simple knowledge, there wouldn't be the death.
I have more such examples and some in my experiences. What are yours?
Still not replying! The Russians got to you, too! "The Russians Did It!"
What is the physics of getting a vehicle unstuck with a strap?
Your turn. It's not a conversation with just one person posting.
