Homework Help: physics

Posted by Katrina on Sunday, October 29, 2006 at 8:11pm.

the cables of a suspension bridge as well as the elements of many man-made structures are designed to behave elastically. can anyone briefly explain to me why it is absolutely necessary that such elements function elastically?

Bridges and other man-made structures are subject to extreme forces of nature.

Wind, sound, water, land etc. all apply force to bridges.

If the bridge is inelastic, it will crack.
