This instruction set will teach you how to design and construct your own bridge made out of balsa wood. This is a fun, intriguing project that will entertain an individual for hours.  Many high school and college science and engineering classes will have projects similar to this one. Keep in mind for those individuals building high school projects that if this design does not meet the particular project specifications, for example truss height and bridge length that is ok. For these individuals the main concept to take from this project is the truss design and how to put the bridge together.

Step 1: Supplies

.The supplies required to complete this project include the following

   • ¼ X ¼ inch balsa wood. This project used five 3ft long sticks

   • One xacto knife
   • A cutting board
   • One pen or pencil to mark measurements
<p>its not o so good but it is a ok</p>
<p>about 15LBS</p>
How much weight does it hold?
<p>like 15LBS</p>
<p>PLEASE tell me how much weight this can hold. my physics grades hangs in the balance~</p>
How much weight does it hold?
<p>Enough to hold a Hot Wheels Car...Well I hope it would.</p>
