The power of the human jaw?

Question

Ok. I never had biology at school, so forgive me for not using the correct terminology. My question is this:

What is the approximate force with which my jaw moves up and down. Please let me know if you don't understand and I will try and rephrase.

Answer 1

the maximum force that a human jaw can bite or close is around 160 pounds ...n sorry i dont know about the opening force.
