This month's Challenge Question: Specs & Techs from IHS Engineering360:
You are a
regular hiker. When you pack your backpack you decide to put the heavier items
close to the bottom of the backpack and the lighter, less dense items near the
top. Is this the best way to pack? Is this scheme good for your body?
And the answer is:
No, this
is not the best way to pack your backpack. You should put the denser, heavier
items at the top of the backpack in order to keep a high center of gravity. Maintaining
a high center of gravity in the backpack prevents large bending angle at your
waist. A smaller bending angle means less strain on the back muscles and the
stomach. Some native tribes have perfected carrying heavy loads on their heads
so that no forward bend is needed.
