&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The following is an archive of the [[Strength of Materials]] website created by Drake Damerau&lt;br /&gt;
----&lt;br /&gt;
The first and only site with extensive, real data for everything having to do with high power hobby rocketry.&lt;br /&gt;
&lt;br /&gt;
How many different times has the question been asked, &amp;quot;What is the best glue?&amp;quot; or &amp;quot;What is the best fin material?&amp;quot; for hobby rocketry. Pose any of those questions to experienced rocket folks, and you&amp;#039;ll receive many different answers from many people. However, there is a clear alternative to the scenario posed above — it&amp;#039;s called real data, and it&amp;#039;s the only way to separate fact from fiction, opinion, views, beliefs, estimations and personal judgments.&lt;br /&gt;
&lt;br /&gt;
By checking out real data on a myriad of different products and materials, you can quickly and accurately gauge what will suit your needs the best. No longer is &amp;quot;Oh, that&amp;#039;ll be good enough&amp;quot; and &amp;quot;Yeah, you&amp;#039;ll be just fine&amp;quot; needed to determine whether or not your rocket will hold together during flight, but simply...&lt;br /&gt;
&lt;br /&gt;
: &amp;#039;&amp;#039;&amp;#039;&amp;quot;In God we trust, all others bring data.&amp;quot;&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
There is no charge for material testing and the data is not sold — this is a free service to the hobby rocketry community. Vendors: send in your material. Do you have great material? Don&amp;#039;t just tell your customers, prove it to them! Click here to submit your material for free testing.&lt;/div&gt;</summary>
