The problem with the question is who`s bridge?. because each bridge is different then each answer will change.
Some bridges will be heavier due to the lumber used by each mock bridge. The moisture content will change depending on the enviroment that each is stored, also unless you use expensive strain gauges to test the weight then again the # will change.
Most people consider a strain guage to be like the scale used to weigh meat or fish but the acuracy is about the same as a good guess.
There are so many variables that the info would not really help.

: Does anybody know the force required to push the bridge down? Maybe the weight or the measurement given by the strain gauge.

: Thanks in advance....
