How much force is required to cut off the blood circulation of, lets say the average human arm? I'm asking because i'm bored and want to try it on myself. I know that in just a couple of seconds with lack of blood flow you will lose complete use of your arm. I'm only going to do this for a second or two with people watching so please do not worry about safety!

    $\begingroup$ If you are losing use of an arm within a couple of seconds that is because you are compressing a nerve and blocking transmission of motor signals, not because of cutting off blood circulation. $\endgroup$ – Bryan Krause Oct 17 '18 at 17:59

The pressure you need to apply is equal to your systolic blood pressure, about 120 mmHg. This is about 163 g/cm^2.
