If you roll up a piece of paper and leave it for years it will stay rolled up. If you leave it rolled up for a minute it is easy to unroll. Of course this must be because the energy stored in that paper when it was first rolled was released in a way other than unravelling. So my question is how does a paper lose its EPE?

  • I think paper has very less elastic limit that's why it will stay rolled up

  • Elastic limit is the maximum strain produced in body from where if unloaded it will regain its orignal configuration

  • But having a low elastic limit doesn't answer how the energy gets released

paper is subject to creep: when an external load is applied, the resulting internal stresses relax slowly over time and the paper takes a set, meaning its original shape is deformed. The set persists even when the external load is removed.

One-line joke

A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
