I am looking for a software where I can draw a bridge. Then I would like it to add stress to the bridge (i.e: add weight to it) and display where the bridge is receiving the most stress. If the software could demonstrate the areas in which the bridge is under tension or compression, it would be even better.

I have a vast experience with computers and a good amount of knowledge in the construction of bridges. I am ready to pay money, so don't limit yourselfs to freeware, please.

Thanks for your recommendations,

CEVfuture

Here is a student's explanation of the evolution of the peppered moth.

At first, all peppered moths were light colored. When pollution began to darken the tree trunks, some light colored moths turned a little darker. These darker moths survived and passed on their darker coloration to their offspring. The offspring became even darker, and their offspring were darker still. This continued until all peppered moths matched the color of the tree trunks.

1) Ammonia (NH3) is widely used as a fertilizer
and in many household cleaners.
How much ammonia is produced when
3:76 mol of hydrogen gas react with an ex-
cess of nitrogen gas? Answer in units of mol.

2) The decomposition of potassium chlorate
(KClO3) is used as a source of oxygen in the
laboratory.
How much potassium chlorate is needed to
produce 15 mol of oxygen? Answer in units of
mol.

3) The elements lithium and oxygen react explo-
sively to from lithium oxide (Li2O).
How much lithium oxide will form if 1:5 mol
of lithium react? Answer in units of mol.

decomposes to form water and oxygen gas.
How much O2 will result from the decom-
position of 2:89 mol of hydrogen peroxide?
Answer in units of mol.

5) Acetylene gas (C2H2) is produced as a result
of the reaction
CaC2(s) + 2H2O(`) !
