Have a look at trunk lids on some cars. They use two transverse torsion rods to hold the lid open. On some models they are adjustable to two or three positions, especially on models with an optional rack or heavy wing or spoiler.
Not as prevalent now as in the 70's and 80's since gas cylinders (that can wear out) have become all the rage. In the 60's and earlier, cars that had trunk lid springs usually used coiled flat springs. Cheaper models had a prop rod or a sliding catch rod which released with a second lift. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
