TESTING THE FREEHAND STRAW BRIDGE
V.Ryan © 2015
 
To test the bridge, place two straight pieces of wood on either side of the bridge and G-cramp them to the bench. This will prevent the bridge from collapsing to either side. weights can then be added to the top, one and a time, until it collapses.
 
 
 
 
 
 
 

Add weights to the bridge, taking care to place them gently.

Record the number of weights your bridge successfully holds and compare the result against other bridges.
