How do we test bridges?

Testing-1.png

Set the bridge on the tester between the two structure support. 

Slide the wood-block into the bridge on top of its roadbed. The wood-block will have a hole to fit over the threaded rod's top, as seen in the image. 

Testing-2.png

Place the washer over the rod, tighten the nut.

Slowly turn the force wheel counterclockwise. 

Apply force until the structure is broken.
