the head is held by an electromagnet

a 100 G at up limit is set to 150 G the
a 100 G at up limit is set to 150 G the value we measured is 125 G so that’s
value we measured is 125 G so that’s
value we measured is 125 G so that’s right in the middle so we can say that

lastly it’s time for the front or chest

centimeter in with this test it’s
centimeter in with this test it’s compressed more like 7 centimeters
nasty stuff but it’s these simulations
nasty stuff but it’s these simulations that save lives and this dummy is a pass
