Free FE and PE practice exams are not widely available, with most users suggesting purchasing study materials for $10-15 instead. The NCEES provides a reference handbook for the FE exam, which can be useful for preparation. Some departments may have example exams, but these are not guaranteed. A user recalls seeing a PDF of an example FE exam but cannot locate it. Overall, investing in official resources is recommended for effective exam preparation.

I would like to know if a free copy is available somewhere. I would also be interested in a free PE exam for electrical engineering.

I have a 30" Fresnel lens that I use to burn stumps it works great.
Tree service wants $2000.
Hi all, i have some questions about the tesla turbine:
is a tesla turbine more efficient than a steam engine or a stirling engine ?
about the discs of the tesla turbine warping because of the high speed rotations; does running the engine
on a lower speed solve that or will the discs warp anyway after time ?
what is the difference in efficiency between the tesla turbine running at high speed
and running it at a lower speed ( as fast as possible but low enough to not warp de discs)
and: i...
