and I just want to ask that will the results still be the same if the downward force is applied to the bottom plane instead of the top plane?

I know that you calculated the strength of the bridge by putting the scale on the top plane of the bridge.

The conditions are...

-the bridge has to be made of 3 mm thick balsa wood and fixed only with balsa glue
-total mass of bridge should not exceed 100 g
-the bridge must support a load of no less than 50 kg

there r loads of other conditions too...but these are the main ones

So anyone who could help us out in where we can started...as in how do we make our structural design, test the bridge etc..it will be most appreciated.

I dont really know where to start. I have not taken into account wind loads for the design of the bridge deck, web verticals, diagonals, or top and bottom chord. However, I have decided to assume a 3.2 kPa wind load for designing the lateral bracing.

My question is: How to i start to design the lateral bracing? Do I assume a distributed load acting on the top chord?]]>
