# AIEEE 2009 Q083 youngs modulus

 Welcome to the Highschool Help Forum! the forum is currently in "Beta" stage of development. You can ask questions and answer/discuss them. The basic functionalities are present. What's required is a more aesthetic look to the Static pages and a more user friendly setup. This will happen over the time gradually as we start creating some content. The site has a lot of tools, like posting mathematical calculations, images and diagrams; categorizing questions and so on. Having them here is NO GOOD unless you know how to use them. I am thoroughly against compiling a list of these features and then writing about them. As soon as you do not understand how to do something or use a certain feature, report that on "How To"s Section of the forum. Your queries will be answered there. If you have any ideas/discussion regarding the site/comments, please go to Discussions regarding Highschool Help Forum Lastly, thanks for joining in the site's development process! It matters!

# Original Question by Vijay Karthik

Here's the question...
 Two wires are made of the same material and have the same volume. However wire 1 has cross-sectional area A and wire 2 has cross-sectional area 3A. If the length of wire 1 increases by Δx on applying force F, how much force is needed to stretch wire 2 by the same amount ? (1) 4F (2) 6F (3) 9F (4) F Posted by Vijay Karthik 13:47, 23 August 2009 (UTC)
