You sould try to have very light pressure on your feet when you sprint. But some people are just heavier on their feet then others. What takes the most pressure is the heal of the foot because it usually hits the ground first. If you want to do sprinting then make sure you get a shoe with good support in the heals. When it comes to running shoes I've found you do get what you pay for.
A pressure treated 6x6 usually weighs around 3.2 pounds per linear foot.
about 2 psi. (0.5 psi / foot of depth)
it takes 76 lbs of pressure to collapse/crush one's windpipe
a gallon or so
it takes 400 dollars
One square foot of water exerts a pressure of approximately 62.4 pounds per square foot at sea level. This is based on the weight of water, which is about 62.4 pounds per cubic foot. The pressure exerted increases with depth, following the principle that pressure is equal to the weight of the water column above the area.
It's called paresthesia. This tingling or numbness occurs when there is prolonged pressure on nerves, leading to temporary disruption in nerve function. It typically resolves once the pressure is relieved and blood flow returns to the affected area.
None at all.
fibula tibula
approximately 12 psi when standing on all fours
An inch is a unit of length. A foot pound is a unit of pressure. The two units are therefore incompatible.
To give you an idea, a 36-foot by 18-foot by 5-foot deep pool takes about 24,000 gallons of water to fill.
