5.2.0. Released
Website version 5.2.0. has been officially released. Hopefully there are no bugs, but that is too much to ask. Nonetheless, I did simulate the environment before I went live, so there should be no major problems. The main page has changed significantly. I think the sections are spaced out more, and are now more clear. The look of the right navigation menu has changed slightly. Also, the function of the last modified note has been changed. Before, I manually updated the date anytime I updated the content of a page. Now, it is automated to update whenever I re-upload a file even if there are no changes at all. I will add a link that explains this. I changed the way the copyright info looks. No biggy.
As I said before, the major change is putting the header, nav, and footer info into php files that I can call at will. This way, they can be changed across the site very easily. This is especially helpful to me as I continually add more pages to the website.
son is builidng a bridge as part of a high school engineering assignment and is struggling.
Is there anything in particular he needs help with?
G’Day Garrett,
Th project is to build a bridge that spans approx one metre and the lengths of wood are approx 80cm and will require joining. Method of joining is PVA glue and tooth picks.
We have many little bridges in our area of Newcastle NSW that are old truss bridges and that provides good examples of what type of truss type was used to construct the bridge.
I’m just curious if there is a formula or program to test the
loads of a proposed bridge prior to construction.

Wayne
Wayne,
The best program I have found is free from John Hopkins University. Here’s a link:
