AI Thread Summary
To learn about engines on a budget, consider posting an ad on Craigslist to find nonworking small gasoline engines like lawn mowers or snowblowers that people are willing to give away. Disassembling these engines provides valuable hands-on experience, and any mistakes made during the process are part of the learning journey. Successfully repairing an engine offers additional satisfaction and knowledge. Additionally, exploring alternative engine types, such as pneumatic engines, can enhance understanding of engine mechanics. Engaging in practical projects is key to effective learning in this field.

I want to learn about engines. Besides reading up on different kinds, what's a good way to get my hands on small gasoline engines, and what kind of things should I do to get some hands on learning?

thanks!

Put an ad out on craigslist for just what you are wanting to do. Somewhere I am sure there are nonworking lawn mowers, snowblowers, etc. that someone would be willing to let you take away. If you get it for free, rip it apart, screw something up, what's the loss? You most likely learned something right? If you get it running, well that's just a bonus.
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
