To get the final torque AND stretch on the bolt, you tighten the bolt a given number of degrees of rotation. This is what the torque angle guage is for, accurately measuring the degrees of additional rotation (typically accurate to a degree or so). The Reason For Not Re-Using Stretch Bolts.
T. rex had a mouth full of serrated teeth; the largest tooth of any carnivorous dinosaur ever found was 12 inches (30 centimeters) long. But not all of the dinosaur's teeth served the same function, according to a 2012 study in the Canadian Journal of Earth Sciences.
Tyrannosaurusâs strong teeth could crunch through the heavy body armor of its prey. Tyrannosaurus had short but muscular arms that helped the animal grab its prey. Tyrannosaurus held its long tail stiffly behind its body. This helped the dinosaur balance itself against its heavy head.
