Brilliant Thankyou. I need to work out something like this for my scoliosis curve so I can determine how much force is on my spine simply holding my head up.

Hi, why does the angle of the torque is 12° ? And does it depends on the angle of how much we bend ? Thanks you for your video, this was very well explained !
Wow that is a lot of torque! So picking up a 160 pound person that threw themselves out of their wheelchair is possibly also 1500 pounds torque at that angle. Versus The Mayo Clinic, Correct way to pick up weight, is holding it tight. And picking up people is very awkward, as they really need to be held in a bear hug position to have the least negative torque on our backs. No wonder everyone has sore backs!!
Exactly. Understanding how the muscular skeleton structure of the human body works makes us realize the enromous forces involved in everyday movement. 🙂
@@MichelvanBiezen , thank you for the quick reply! Is there a training video for my committed workers and me? For short term work, the idea is to be able to show people that they can lift bigger loads than they think they can. So by bear hugging the client (who’s ankle just broke) out of the wheelchair, the 150 pound client torque might be lowered to only 300#s? Or is it 500? Or 750? Which is much more than the 20-50# I usually limit myself to?
@@MichelvanBiezen , on a separate thought; As a Geoscientist student I was gifted with having a Professor of Geochemistry that studied pole rotation in rocks. So, with the coming catastrophic pole change. I’m envisioning water surging through the Earth as the whole mantle is destroyed and eruptions and tsunamis occur. So that maybe a few people survive. For mass production, could a commercial washer be turned into a single use tsunami pod? Possibly by adding an air input where the water input enters? Just for mental gymnastics…
On your first question. The studty of physical therapy will cover all those types of situations, that is their specialty. On your second question, when the magnetic poles of the Earth shift it will not result in any "catastrophic" events.

It definitely opens our eyes to the application on our own body.

Thank you, Sir! You're absolutely amazing
You're very welcome!
Hi Mr. Michel,
Please, where book do I find these exercises? Have a nice day and the great job you have done.
All the major physics texts used in college will cover all of this material in great detail. Understanding them can be challenging at times.

That is a good approximation of the body mechanics.

is the weight of head is included if we have the centre of mass
It should be included.
Hi, are the problems related to physics and body mechanics coming from a certain book? Thank you.
These are typical examples that can be found in many text books as well as made up problems to aid the understanding.
Ok,thank you. I find these very useful.
doesn't the arm give an upward force as well?
oh boy. I hope you got the answer by yourself after three years.
my lord =thank u for very good lecture =please name book =amarjit =india
We don't follow any partiular book. The videos are based primarily on our formulated problems, and from a number of sources.
