Qual è la differenza tra riveting e gripping ?Sentiti libero di rispondere con un esempio.

Gripping is clasping, wielding, holding something tightly and forcefully (usually with extremities)

Riveting is a (somewhat obsolete) construction technique, that entails bolting metal (usually steel) girders together with red-hot bolts, that are fired at great pressure from a riveting-gun.

Figuratively speaking, both denote, albeit slightly differently, fascinating or enthralling one's audience.
"The movie was so intense that the viewers were riveted to their seats, watching it in pure astonishment. It went so far as to even grip their minds for several weeks afterwards"
