Testing Bridge REALY NEED HELP
 
OK if you are reading this then you know that my project is on bridges. First of all i an a grade 7 and i ran out of topics so i had to do the first thing that came to my mind:What is the strongest type of bridge. now as i told my classmates about it they said that it was too easy and learned this stuff in grade 3(which is true) so my old design to put math text books on it is bad and i am
Wondering if anyone got any ideas on how to test the strength of the bridges or somehow make my old idea more complicated than it needs to be. THANK :embarassed::star:YOU

Ps: the types of briges i am doing are the arch truss and beam
