Need a realistic Statics Problem

[sanddrag]

I need to take a realistic situation, simplify it, and analyze it as a statics problem. It doesn't have to be super complicated, it just needs to be a good problem to illustrate the principles of vector statics. I was kind of thinking of doing some sort of 3D problem, but I was also thinking it would be cool to analyze something like the arm of a backhoe tractor (in a simplified 2D way).

Areas of study include trusses, friction, force and moment equilibrium, and frames and machines.

I'd kind of prefer a force and moment equilibrium problem but I'm open to any suggestions.

I need a problem that is not too difficult, but not too easy.

Thanks.
