Asquare steel plate is 10.0 cm on a side and 0.500 cm thick. (a) find the shear strain that results if a force of magnitude 9.0 × is applied to each of the four sides, parallel to the

Shear stress on the steel plate is given by

now in order to find shear strain we can use

shear modulus of steel is given by

now by above formula we will have

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
